What K&J Magnetics does

K&J Magnetics, Inc. is a privately held US-based online retailer specializing in neodymium (NdFeB) rare earth permanent magnets. Founded and operated from Pipersville, Pennsylvania, the company has been selling the strongest commercially available grades of neodymium magnets — including N35, N42, N52, NAH, and NSH high-temperature grades — for over 20 years. Its catalog spans disc, cylinder, rod, block, cube, bar, ring, mounting, hook, fishing, closure, countersunk, diametric, sensor, levitation, and educational magnet formats, with multiple coating options (nickel, plastic, rubber, silicone, epoxy, gold, black nickel, zinc, stainless steel).

The company maintains a stated inventory of over 100 million magnets at its single Pipersville warehouse and offers same-day shipping on orders placed by 1PM EST, Monday through Friday. It supplements catalog sales with free online engineering tools — pull force, repelling force, magnetic field, steel thickness, gap, BH curve, and unit-conversion calculators — as well as free CAD drawings, certifications, and direct application advice from in-house magnet engineers. Custom neodymium magnet design and manufacturing services are also offered.

K&J Magnetics sells exclusively through its own website at kjmagnetics.com, with no distributor or reseller channels. Pricing is per-unit with automatic quantity discounts at checkout and a "buy more, save more" bulk purchasing model. The customer base is horizontal and fragmented — spanning commercial and industrial users, hobbyists and DIY customers, home and office buyers, educators (including school science kits), and electronics/sensor engineers — with transactions being one-time purchases rather than subscriptions. Payment methods include major credit cards and PayPal; sales-tax-exempt accounts are available for qualifying businesses.
