Abstract

Abstract: In this paper，the magnetic field distribution along the axis of a finite permanent magnetic cylinder uniformly magnetized in its axial，diametrical and arbitrary directions，and the magnetic field distribution in the whole space of an infinite permanent magnetic cylinder uniformly magnetized in its axial，diametrical and arbitrary directions have been systematically calculated in the view of molecular current and magnetic charge.

Key words: uniform magnetization, permanent magnetic cylinder, the magnetic field, magnetic charge
