Neodymium-iron-boron (NdFeB) enables very strong magnets at relatively low cost. The production takes place via powder metallurgical processes, but today increasingly as plastic-bonded magnets. For a long time, the operating temperatures were limited to a maximum of 60-120 ° C. For some recent developments, operating temperatures up to 200 ° C are specified. Magnetic material consisting of neodymium, iron and boron.

A neodymium magnet is a particularly strong magnet. These supermagnets are also known as neodymium-iron-boron magnets. Neodymium Magnets - So rare earths - are more expensive than conventional magnets due to their elaborate production technology. But they are among the strongest of their kind. These and other magnets, such as hook magnet, telescope magnet, ring magnet or disc magnet leads the well-known magnet shop. As a leading supplier, the company is also strong in the field of school magnets, industrial magnets and magnetic films.
In order to make field lines (or lines of force) visible in school lessons, the bar magnet is used. Iron powder is best suited for this visualization. The magnetic color is selectable for many items. The school classic is red / green (N / S).
Magnets, which leads magnet-shop can also be used, for example, on a whiteboard, on a magnetic board, as a pin board magnet or as a office magnet.
