Basic conception of Magnet (I)
BrA magnet in a closed environment, magnetized by an external magnetic field to the technical saturation after the withdrawal of the external magnetic field. At this time sintered Ndfeb magnet performance of magnetic induction strength. Generally speaking, it can be temporarily understood as the magnetic force of the magnet after magnetization.The relationship between Br and surface magnetism: both are in Gauss, but there is no corresponding relationship between surface magnetism and Br, that is, two magnets with the same Br, the size of the surface magnetism may not be the same, and the surface magnetism is affected by the shape, size and magnetization of the magnet.HcbWhen the magnet is reversely magnetized, the value of the reverse magnetic field strength required to reduce th...
