Abstract
This paper studies distribution characteristics of paraxial magnetic field of solenoid with inner relaxation polarization medium and driven by ac signal. Firstly, the paraxial electromagnetic field model of hollow solenoid was constructed by Maxwell equations, and the influence of the driving signal frequency was analyzed. Then, based on the established paraxial electromagnetic field model of hollow solenoid, the magnetic field model of solenoid with inner relaxation polarization medium was established by ampere loop law. Finally, the effects of relaxation polarization medium and driving signal frequency on magnetic field amplitude and phase shift were analyzed in detail. The conclusions were drawn as follows: driving signal frequency affects magnetic field amplitude; the relaxation polarization medium will cause the phase shift of magnetic field; and the phase shift will increase as the driving signal frequency increases.
