Black strong magnets usually refer to neodymium iron boron permanent magnets with a black appearance, because black ferrite magnets are not considered strong magnets. This sample has a length of 20mm, a width of 6mm, and a thickness of 1mm. The default thickness direction magnetization is supported, and the size can be customized. If thicker or thinner points are needed, there is no problem. The magnetic performance level can be selected according to your needs. If you need to use it in high temperature environments, you need to choose a temperature resistance level, which can be used up to 220 degrees Celsius.
