Abstract

By solving Laplace equation of several areas in spherical coordinates，we get scalar magnetic potential and magnetic field distribution that produced by a rotating charged body at constant angular speed. Then the magnetic strength of the rotating disc’s center，the rotating disc’s axis，the rotating disc’s far field and near region are obtained.

Key words： scalar magnetic potential; Laplace equation; magnetic field distribution
