A Leader in the Field of Magnetics

Adams Magnetic Products has been engineering and manufacturing magnetic products since 1950. We are a custom manufacturer, fabricator, and distributor of all types of permanent magnets, magnetic assemblies, and devices: alnico, ceramic, flexible magnets, neodymium, samarium cobalt, rare earth, magnet assemblies, stock or custom. Choose from our millions of magnets in stock, or let us make your custom design.

Adams’ History

A pioneer in permanent magnet fabrication, Leo Weinstein opened the doors of the Adams Magnetic Products Chicago facility in 1950, naming it Adams for more prominent placement in the phone book. Over the next 70 years, Adams would become an industry leader, working with more than 100,000 customers, including many Fortune 500 companies. This growth was the result of a dedication to our customers’ needs and a commitment to innovation, including an expansion into flexible magnetic products in the 1960’s and 70’s, the fabrication of alnico and rare earth magnets and complex custom-engineered assemblies in the 1980’s, a foray into the soft ferrite market in the 1990’s, the addition of a dedicated office in Beijing, China in 2007, and the introduction of a wide format magnet sheet in the 2010’s, among countless other strategic – and successful – decisions. Weinstein’s commitment to integrity, respect, excellence, and responsibility lives on today, as do his round base and channel magnetic assemblies.

Custom Magnets, Magnetic Assemblies

Our in-house magnet manufacturing machine shop has capabilities for cutting, surface grinding, OD grinding, and ID grinding most magnet materials to print specifications. We also work with Wire-EDM facilities for cutting complex magnet shapes out of raw materials.

We have the capabilities to produce magnets of virtually any shape and size to customer specification. And we can provide precision-machined metal (and other) components to create custom magnet assemblies. Additionally, our state of the art testing apparatus and fully equipped testing lab verify the high quality of all the magnets we produce.

Lead times for custom magnets depend on the complexity of the job, the quantity required, raw material availability and shop load. However, we can complete custom orders within 2 to 4 weeks, and sometimes in as little as a few days.
