NdFeB----the most powerful magnet2018-08-20
Unlike other magnets, neodymium magnets are not as demagnetizable as magnets of other materials and have particularly strong magnetic properties. It can retain the magnet properties for more than ten years and is called the permanent magnet magnetic king. NdFeB magnets require very high excitation fields.
The properties of sintered NdFeB are hard and brittle, and the surface is prone to corrosion. Therefore, magnet manufacturers recommend that the surface of the magnet be coated.
NdFeB magnets are widely used in life and industry. The shape can also be customized, such as squares, cubes, cylinders, rings, trapezoids and so on.
