Demagnetization field

Operating Point, Load Line and Permeability Pc of Permanent Magnet The permanent magnet works in the open circuit state. Since the magnet in the open circuit state is under the action of the demagnetization field, the magnetic induction intensity of the permanent magnet in the working state is not at the Br point in the [...]

Anisotropy of Permanent Magnet Shape and Demagnetization Field and Demagnetization Factor Make the permanent magnet into a certain shape. Take the block magnet in the following figure as an example. If you measure the magnetization curve in the open circuit state along the x, y, and z directions of the magnet, you can find that [...]
