5 PIECES N52 Neodymium LONG THIN Bar Magnet 30mm L x 10mm W x 1mm Thickness Super Strong Rare Earth NdFeB Bar Magnet for School, Science, Physics Projects Experiments and Magnet Inventions

Neodymium magnets can be found on the market with the name of magnets neodymium iron boron, or NdFeB magnets. Neodymium is part of that category of materials known as "rare earths." The name of the rare earths is not due to their concentration in nature but to the difficulty which occurs in the separation of these from other materials with which they are linked through chemical bonds. For this reason, it can be said that the neodymium magnets are not the cheapest but their magnetic force is among the most powerful, this power is found already in a magnet of few centimeters. What you need to do is look for the form most suited to you. We offer the following forms: disks, cones, rings, cylinders, cuboids and blocks, cubes and spheres. Even our self-adhesive magnets are versatile for many uses because they stick practically everywhere.
