Neodymium Block Magnets — N52 Rectangular & Square NdFeB Rare Earth Magnets
JC Magnetics stocks neodymium block magnets in N52 grade across a wide array of rectangular and square profiles, from compact 5×5×1mm wafers to large 50×25×10mm bars. N52 block magnets deliver the highest energy product available in standard rectangular geometry, making them the preferred choice for holding fixtures, magnetic clamping jigs, fabrication tooling, whiteboard and display mounting, cabinetry latches, and robotics end-effector assemblies. The rectangular geometry also makes block magnets ideal for linear actuator design, magnetic separation equipment, and custom magnetic circuit construction. Each unit is plated with Ni-Cu-Ni for surface protection and dimensional consistency. Engineers and fabricators rely on our N52 block magnets for applications requiring predictable, repeatable pull-force specifications across production runs.
