Remagnetization of permanent magnets in closed and open magnetic circuits
The homogeneity of the strength of the magnetic field on the surface of a magnet placed in open and closed magnetic circuits is investigated using a program for modeling the remagnetization processes in highly anisotropic uniaxial ferromagnets. It is shown that the inhomogeneity of the magnetic field on the surface of a magnet is a consequence of magnetostatic interaction between the magnet’s microvolumes. A comparison of the calculation results and experimental data shows their close resemblance.
