Adams Magnetic Products

What Adams Magnetic Products does

Adams Magnetic Products is a U.S.-headquartered industrial magnet company founded in 1950 and based in Elmhurst, Illinois, that engineers, manufactures, and distributes permanent magnets and custom magnetic assemblies. Its product portfolio spans five core magnet material families (neodymium NdFeB, samarium cobalt SmCo, alnico, ceramic ferrite, and flexible polymer-bonded magnets) in standard shapes (disc, ring, block, bar, horseshoe) and value-added configurations including round base (pot) magnets, channel assemblies, sandwich assemblies, electromagnets, magnetic latches, and matched-pole strips. Sub-branded product lines (TabMAG, GreenMAG, MegaMAG, MAGbond, EdgeMAG, MatchMAG, FoilMAG) target packaging, print graphics, and signage applications alongside core OEM usage.

The underlying technology is centered on magnetic circuit design and assembly engineering rather than software or AI. Adams applies magnetic circuit analysis, finite element analysis (FEA) simulation, magnetic characterization, and quick-turn prototyping to engineer custom assemblies that integrate permanent magnets with steel housings, channels, and other structures. Capabilities are gated by ISO 9001:2015 quality certification and ITAR registration with the U.S. Department of State, enabling service to aerospace, defense, and medical device customers. Manufacturing facilities operate in Illinois (headquarters), Carlsbad, California, and Beijing, China, with dedicated sales offices in Los Angeles, Chicago, Louisville, and New York.

The business model is primarily direct, sales-led B2B. Revenue streams come from sale of stock magnet products and assemblies (unit pricing by size, type, and quantity), custom-engineered magnets and assemblies (quote-based), engineering and prototyping services, and vendor-managed inventory programs. Pricing is quote-based and not publicly disclosed. Go-to-market combines inside sales (phone, email, contact forms) with technical engineering consultation supporting OEM customers in industrial manufacturing, medical devices, aerospace and defense, automotive (notably EV motors and power steering), renewable energy, fasteners and packaging, and music/audio equipment. The company is privately held following its November 2023 acquisition by High Street Capital.
