General-Purpose Neodymium Magnets – Strong, Versatile, and Easy to Use
Applied Magnets’ 40 × 40 × 20 mm neodymium block magnet delivers strong magnetic attraction for workshop fixtures, displays, woodworking, magnetic closures, and DIY assemblies.
Made from neodymium iron boron (NdFeB), this rare earth magnet provides greater magnetic strength than a similarly sized ferrite or ceramic magnet and offers a cost-effective choice for projects that do not require higher-grade neodymium material.
