The measurement principle for the surface of magnetic field intensity distribution of the radial magnetizing ring alnico is introduced,and the internal relations between surface of magnetic field intensity distribution and reference waveform are derived.

The anisotropic bonded NdFeB magnets were prepared by die-upsetting process and the effect of surface residual magnetization of anisotropic bonded magnets which were demagnetized by alternating current demagnetization and heat demagnetization process on the quantity of magnetic powder attracted on the surface was investigated.

surface magnetic currents are approxi- mated by the currents on circular cylinder,and when e>0.

Based on the approximation of the surface distribution of the ground current due to the skin effects and of the equivalence between the surface magnetic field and surface current density, this paper designs a novel magnetic field measurement apparatus which is applied to the test of th.

For S polarization,the angular distribution of fast electrons can be explained by taking account of the surface magnetic field qualitatively.

In this paper we consider the effect of deposition in calculation critical properties of magnetic surface Clock model by Monte Carlo simualtion.
