Why Choose JC Magnetics for Your Rare Earth Magnet Needs?

JC Magnetics is a Brooklyn, NY-based supplier of high-performance neodymium rare earth magnets, serving engineers, fabricators, hobbyists, educators, and industrial buyers across the United States. Our catalog covers every major permanent magnet geometry — disc magnets, block magnets, cylinder magnets, ring magnets, countersunk magnets, cube magnets, and sphere magnets — with a focus on premium N52 and N55 grades.

The Strongest Permanent Magnets Available

Neodymium magnets (NdFeB — neodymium iron boron) are the strongest type of permanent rare earth magnet on the market. All JC Magnetics products are manufactured from sintered NdFeB alloy and finished with triple-layer nickel-copper-nickel (Ni-Cu-Ni) plating for corrosion resistance, unless otherwise specified in epoxy-coated or gold-plated variants.

N52 & N55 — Maximum Performance Grades

The "N" grade number directly reflects the magnet's maximum energy product (BHmax). JC Magnetics specializes in N52 — the most widely used high-performance commercial grade — and N55, the strongest sintered neodymium grade currently available, delivering up to 10% more pull force than N52 at equivalent dimensions. Whether you're building a precision motor assembly, a magnetic separation system, or a heavy-duty retrieval rig, our N52 and N55 stock gives you the strongest option without custom lead times.

Specialty Lines & Industrial Orders

Beyond standard shapes, we offer epoxy-coated waterproof magnets, gold-plated decorative magnets, diametrically magnetized cylinders for BLDC motor and encoder assemblies, countersunk mounting magnets, and high-pull fishing magnets. Bulk and OEM inquiries are welcome. We also carry 3M VHB double-sided adhesives and magnetic stainless steel accessories. All in-stock orders ship fast from our Brooklyn, NY warehouse.
