| Abstract: | In the Rayleigh's region, a mathematical physics model is set up which can be used to describe the relation of the remnant magnetization of a magnetic body with the applied varying magnetic field. An analytic formula is derived which represents the influence of attenuation ratio on the remnant magnetization of a magnetic body after the deperming process with a magnetic field of declining amplitude of equal attenuation ratio. The nonlinear magnetization property or the hysteresis characteristics of magnetic material is related to the varying magnetic field in the synthetic deperming process which in some aspects demonstrates that different deperming standard limits the value of the attenuation ratio. |
