field coil
6.In order to research the compatibility of a large-scale degaussing station, this paper analyzes the compages of ampere turns of compensating coil based on the calculation of magnetic field about degaussing coil. And the problem of the distribution of magnetic field sensors is put forward, and is then sovled.
7.ANALYSIS AND CALCULATION FOR RADIAL MAGNETIC FIELD OF TOROIDAL EXITING COIL INSIDE ROTATING ARC WELDING MACHINE
10.In the anistropic magnetic medium under the condition of magnetic permeability μ11unequal to μ33,the magnetic field on axis line of current-carrying coil and that inside current-carrying solenoid can be calculated by applying Biot-Savart law of that medium.As the condition of their service is restricted,it is necessary to derive the magnetic field on axial line of current-carrying coil and that inside current-carrying solenod under more general condition of μ11unequal to μ33.On the basis of the magnetic field on axial line of current-carrying coil in anisotropic magnetic medium under the derived condition of μ11unequal to μ33,the authors obtain the magnetic field on axial line of current-carrying solenoid in anisotropic magnetic medium under general condition of μ11unequal to μ33.The result shows a wider applicable coverage.
