Neodymium magnet is the strongest magnet in the world till now that can lift up to 1000 times its own weight, it is mainly made of Neodymium, Iron and Boron. It is high remanence, high coercive force, high energy product and high performance/cost ratio. Neodymium magnet is anisotropic and only magnetized in one direction.
