Block & Cube Magnets

  Neodymium (Neo or NdFeB) magnets are permanent magnets, and part of the rare-earth magnet family. are the strongest permanent, rare-earth magnets commercially available today with magnetic properties that far exceed other permanent magnet materials. Their high magnetic strength, resistance to demagnetization, low cost and versatility make them the ideal choice for applications ranging from industrial and technical use to personal projects.

  Neodymium bar, block and cube magnets are incredibly powerful for their size, with an approximate pull strength of up to 300 lbs. Neodymium block magnets in rectangular, square and cube shapes. are made in a variety of sizes and grades to meet all types of applications.

  Neodymium Block Magnets are also widely used in applications like building kits, conveyors, clamps, closers, filters, metal detectors, cell phones, loudspeakers, flow meters, hybrid and electric vehicles, wind turbines, and motors in cordless tools.
