        This Prospectus relates to 4,200,000 shares (the "Securities") of Common Stock, par value $.01 per share ("Common Stock"), of Magnetek, Inc., a Delaware corporation (the "Company" or "Magnetek"), which may be offered for sale from time to time by the stockholders listed herein (the "Selling Stockholders"). The Selling Stockholders acquired the Securities pursuant to a private transaction. The Company is registering the Securities in order to provide the Selling Stockholders with freely tradable securities pursuant to Registration Rights Agreements (we refer to collectively as the Registration Rights Agreements) between the Company and the Selling Stockholders. The Company will not receive any of the proceeds from the sale of the Securities by the Selling Stockholders. The Company is required to pay most of the expenses of the registration of the Securities, including, registration fees and legal and accounting fees. Underwriting discounts, commissions, fees and transfer taxes will be the responsibility of the Selling Stockholders. See "Selling Stockholders."

        The Common Stock is listed on the New York Stock Exchange ("NYSE") under the symbol "MAG." On November 11, 2003, the last reported sale price per share of the Common Stock, as quoted on the NYSE, was $6.52.

See "Risk Factors" beginning on page 2 of this Prospectus and those risk factors contained in the applicable prospectus supplement, if any, for considerations relevant to an investment in the Securities.

        The Selling Stockholders may from time to time offer and sell the Securities held by them directly or through agents or broker-dealers on terms, including the price per share, to be determined at the time of sale. To the extent required, the names of any agent or broker-dealer and applicable commissions or discounts and any other required information with respect to any particular offer will be set forth in an accompanying Prospectus Supplement. The Selling Stockholders reserve the sole right to accept or reject, in whole or in part, any proposed purchase of the Securities to be made directly or through agents.

        The Selling Stockholders, and any agents or broker-dealers that participate with Selling Stockholders in the distribution of Securities or are Selling Stockholders may be deemed to be "underwriters" within the meaning of the Securities Act of 1933, as amended (the "Securities Act"), and any commissions received by them and any profit on the resale of the Securities may be deemed to be underwriting commissions or discounts under the Securities Act. See "Plan of Distribution."

THE COMPANY

        The Company supplies digital power-electronic products used in information technology and industrial, communications, consumer and other markets. These products usually take the form of sub-systems. They are sold directly or through agents to original equipment manufacturers ("OEMs") for incorporation into their products, to system integrators and value-added resellers for assembly and installation in end-user systems, and to distributors for resale to OEMs, contractors and end users for repair and replacement purposes. Founded in July 1984 and listed on the NYSE in July 1989 (NYSE: MAG), Magnetek operates six factories in North America, two in Europe and one in China, together employing approximately 1,700 people worldwide. The Company's principal executive offices are located at 10900 Wilshire Boulevard, Suite 850 Los Angeles, California 90024-6501, telephone number (310) 208-1980. The Company maintains a World Wide Web site at http://www.magnetek.com.

RISK FACTORS

Certain information set forth or incorporated by reference in this Prospectus includes "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995 and is subject to certain risks and uncertainties, including those identified under this caption. Readers are cautioned not to place undue reliance on these statements, which speak only as of the date hereof. The actual results of the Company may vary materially from those anticipated in the forward-looking statement. The Company undertakes no obligation to release publicly any revisions to these forward-looking statements to reflect events or circumstances after the date hereof or to reflect unanticipated events or developments.

In addition to the other information included elsewhere in this Prospectus, the following factors should be considered carefully in evaluating an investment in the Securities offered by this Prospectus.

General market conditions can effect our results of operations. Also, general business risks facing public companies may effect our business.

        A continuing low level of demand for power products in the telecommunications and information technologies industries had an adverse effect on the Company's operating results in fiscal 2003. If demand in one or both of these industries deteriorates further in subsequent periods, the adverse effect on our results of operations could continue. In addition, we are subject to all of the business risks facing public companies, including business cycles and trends in the general economy, financial market conditions, changes in interest rates, demand variations and volatility, potential loss of key personnel, supply chain disruptions, government legislation and regulation, and natural causes.

We rely significantly on our top five customers and the loss of any one of them can negatively affect our financial position or results of operations.

        Sales to our top five customers represented approximately 30% of its net sales in fiscal 2003. The loss of any such customers or significant decreases in any such customers' levels of purchases from us could have a material adverse effect on our financial position or results of operations.

We face risks associated with the fact that some of our competitors are substantially larger and have greater resources that we do.

        The power supplies industry includes more than 1,000 enterprises, according to MicroTech Consultants, an industry research organization. Of these, we compete directly only with manufacturers of complex, non-commodity power products, which management estimates constitute less than 5% of the industry. However, some of our competitors are significantly larger and have substantially greater resources than we have. Further, given the current excess capacity and the decline in valuations of companies within the industry, the risk of consolidation in the industry could result in larger competitors than exist today.

2

        In power systems, we compete with crane and hoist drive manufacturers and drive system integrators, elevator drive manufacturers and control system integrators, mining machinery drive builders, power inverter builders and telecom power systems builders. The total number of such enterprises with whom Magnetek competes directly is considered to be fewer than 100. However, some of Magnetek's competitors are significantly larger and have substantially greater resources than Magnetek, and some are global in scope, whereas Magnetek currently competes primarily in the North American market.

Our international operations are subject to risks associated with changes in local economic and political conditions, codes and standards, currency exchange rates and restrictions, regulatory requirements and taxes.

        Since international sales currently account for nearly half of our revenue, currency exchange rates impact our results. This is partially a currency translation issue with no economic impact on actual results. However, a fluctuation in exchange rates between a foreign currency and the U.S. dollar can have an economic impact on revenue and profit. During fiscal 2003, Magnetek was impacted by currency fluctuations, primarily the weakening of the U.S. dollar against the Euro. Additional weakening in the value of the dollar against other currencies, primarily the Euro, could have an adverse effect on our financial results.

        In addition, we expect to continue to migrate production to our lower-cost facility in China and increase the use of outsourcing, which could result in production delays or quality issues during the transition. Problems associated with such transitions may result in delays of shipments to customers, cancellations of delayed shipments, diversion of management attention, increases in inventory levels, increases in quality issues, increases in warranty returns and an inability to achieve anticipated manufacturing cost reductions, any of which could result in an adverse effect on our business, operating results and financial condition.

        Moreover, the supply and cost of these products could be adversely affected, among other reasons, by changes in foreign currency exchange rates, increased import duties, imposition of tariffs, imposition of import quotas, interruptions in sea or air transportation, political or economic changes, anti-terrorism initiatives and risks associated with hostilities. In the event of confiscation, expropriation, nationalization or governmental restrictions in the above-mentioned locations, earnings could be adversely affected by such business disruption, resulting in delays and/or increased costs in the production and delivery of products.

Our industry is reliant on intellectual property. If we are unable to maintain technological competitiveness or if we are found to have infringed upon intellectual property of others, our business operations could suffer.

        We believe that our intellectual property in the area of digital power-electronics is equal or superior to our competitors' and we do not know of any new technologies that could cause a shift away from digital power-electronic solutions. However, as a technology-based company in an industry characterized by short product life cycles, Magnetek is dependent on both patented and proprietary intellectual property. Therefore, major advancements in digital power-electronic technology by competitors or the advent of technologies obviating digital power-electronic solutions could have an adverse effect on our business.

        We could also be adversely affected financially if we are found to have infringed upon the intellectual property of others. We are currently defending against one such claim alleging infringement of electronic ballast patents.

3

Environmental liabilities associated with operations that we have divested may have an adverse effect on our financial position.

        Magnetek has agreed to provide indemnification against environmental liabilities and potential liabilities associated with operations that it has divested, including certain motor, generator, lighting ballast, transformer and drive manufacturing operations. Such liabilities, if any, could have an adverse effect on our financial position. Further, we have been indemnified against potential environmental liabilities and potential liabilities associated with operations we have acquired, including lighting ballast, transformer, capacitor and crane brake manufacturing operations that were subsequently divested. If not paid for by the indemnifiers such liabilities, if any, could have an adverse effect on our financial position.

We may pursue acquisition opportunities which could detract from our other businesses or could fail. Also, our credit facility restricts our ability to make acquisitions without our lender's consent.

        Our business strategy has historically called for growth and diversification in the digital power-electronic products business. Pursuing acquisition opportunities and attempting to integrate and manage acquired businesses requires significant resources, including management time and skill, and these efforts may detract from the management or operation of these and our other businesses. Additionally, acquired businesses may not perform as anticipated, thereby causing our operating results to suffer. In addition, in August 2003 we entered into a $19 million credit facility with Bank One, NA. Our credit agreement restricts us from making acquisitions, and we cannot be sure that the lender will consent to any particular proposed acquisition.

USE OF PROCEEDS

        The Securities are being offered for the account of the Selling Stockholders. The Company will not receive any of the proceeds from the sale of the Securities offered hereby.

PLAN OF DISTRIBUTION

        Sales of Securities may occur in one or more of the following types of transactions (including block transactions): transactions on the NYSE or any other organized market or quotation system where the securities may be traded; transactions pursuant to Rule 144 of the Securities Act; other privately negotiated transactions between a Selling Stockholder and a purchaser; or transactions effected with or through a broker-dealer acting as either agent or principal.

        These transactions may involve the transfer of the securities upon exercise or settlement of put or call options, or the delivery of the Securities to replace securities that were previously borrowed from another stockholder or a combination of such methods. If a broker-dealer is used in the sale of the securities, that person may solicit potential purchasers. The Securities may also be transferred as a gift, distribution or as a result of a pledge, or may be sold to a broker-dealer acting as principal. These persons may then sell the Securities to another person, either directly or through another broker-dealer, subject to compliance with the requirements of the Securities Act.

        The price at which sales of the Securities occur may be based on market prices or may be negotiated between the parties, and the consideration may be cash or another form negotiated between the parties. Broker-dealers acting as agents or principals may be paid compensation in the form of discounts, concessions or commissions from the Selling Stockholder and/or from the purchasers of the securities, or both. Brokers or dealers may be deemed to be "underwriters" within the meaning of the Securities Act. Any profits on the resale of the Securities by a broker-dealer acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, that can be attributed to the sale of the Securities will be paid by the Selling Stockholder and/or the purchasers. The Company has agreed to pay certain of the costs, expenses and fees of preparing, filing and maintaining this Prospectus, but the Company will not receive any proceeds from the sale of the Securities. The Selling Stockholders may agree to indemnify any agent, dealer or broker-dealer for the sale of the Securities, the Company will, if required, file a supplement to this Prospectus.

        The Selling Stockholders have advised us that they have not entered into any agreement, understanding or arrangement with any underwriters or broker-dealers regarding the sale of the Securities, nor is there an underwriter or coordinating broker acting in connection with a proposed sale of the Securities by the Selling Stockholder. If the Company is notified by any Selling Stockholder that any material arrangement has been entered into with a broker-dealer for the sale of the Securities, the Company will, if required, file a supplement to this Prospectus.

7

        If the Selling Stockholders use this Prospectus for any sale of the Securities, they will be subject to the prospectus delivery requirements of the Securities Act. For transactions effected on or through the NYSE, those requirements may be satisfied by our delivery of copies of this prospectus to the NYSE in compliance with Rule 153 of the Securities Act. Instead of using this Prospectus for any sale of the Securities, a Selling Stockholder may resell the Securities in compliance with the criteria and requirements of Rule 144 of the Securities Act.

        The anti-manipulation rules of Regulation M under the Securities Exchange Act of 1934 may apply to sales of the securities and activities of the Selling Stockholder.

Item 15. Indemnification of Directors and Officers

        The Registrant's Restated Certificate of Incorporation provides that a director of the Registrant shall not be liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, including grossly negligent business judgments made in good faith, except for liability (i) for breach of the duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the Delaware General Corporation Law (governing distributions to stockholders), or (iv) for any transaction for which a director derives an improper personal benefit.

        As permitted by Section 145 of the Delaware General Corporation Law, the By-laws of the Registrant provide that the Registrant is required to indemnify its directors, officers, employees and agents, and persons serving in such capacities in other business enterprises at the Registrant's request, to the fullest extent permitted by Delaware law, including those circumstances in which indemnification would otherwise be discretionary (except that the Registrant is not required to indemnify a person who (i) acted in bad faith, (ii) failed to act in a manner such person reasonably believed to be in or not opposed to the best interests of the Registrant, (iii) in the case of a criminal proceeding, had reasonable cause to believe that such person's conduct was unlawful, or (iv) in the case of an action or suit by or in the right of the Registrant, has been adjudged liable for negligence or misconduct in the performance of such person's duty to the Registrant unless an appropriate court determines that such person is entitled to indemnity). Notwithstanding the foregoing, the Registrant is required to indemnify the expenses incurred by any director, officer, employee or agent who has been successful on the merits or otherwise in defense of any action, suit or proceeding. The Registrant may, but is not required to, advance expenses of a director of officer incurred in defending an action suit or proceeding provided that the Registrant receives an undertaking that such director or officer will repay the advanced funds in the event it is ultimately determined that such person is not entitled to indemnification. Indemnification under the Registrant's By-laws may only be made upon a determination by a quorum of disinterested directors (or, in certain circumstances, by independent legal counsel or the stockholders) that indemnification is proper in the circumstances because the applicable standard of conduct has been met. The indemnification provisions contained in the Registrant's By-laws may be sufficiently broad to permit indemnification of the Registrant's officers and directors for liabilities arising under the Securities Act.

II-1

        The Registrant's By-laws also provide that the rights to indemnification provided for in the By-laws are not exclusive of any other rights to which those seeking indemnification may be entitled under any by-law, agreement, vote of stockholders or disinterested directors, and further provide, in accordance with Section 145 of the Delaware General Corporation Law, that the Registrant may purchase and maintain insurance which protects its officers, directors, employees and agents, and persons serving in such capacities in other business enterprises at the Registrant's request, against any liabilities incurred in connection with their services in such capacities. Such an insurance policy has been obtained by the Registrant.

        The description of the Registrant's By-laws contained in the preceding paragraphs is qualified in its entirety by reference to the Registrant's By-laws (filed with the Commission as Exhibit 3.2 to the Registrant's Annual Report on Form 10-K for the fiscal year ended June 30, 2003, which is incorporated by reference herein).

        The Registrant has agreed to indemnify certain directors and officers of the Registrant for any damages suffered in connection with the exercise of certain registration rights.

Item 17. Undertakings

        The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or

II-2

Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered thereby and the offerings of such securities at the time shall be deemed to be the initial bona fide offering thereof.

        Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matters has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

        The undersigned registrant hereby undertakes:

        (1)   To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement;

        (i)    To include any prospectus required by Section 10(a)(3) of the Securities Act;

        (ii)   To reflect in the Prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;

        (iii)  To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement;

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement.

        (2)   That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        (3)   To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
