Abstract

In this paper, a simple method for calculating the interaction energy of multiple uniform magnetized permanent magnet spheres is presented based on the magnetic charge view. Then, based on this method, we calculate and compare the relative stability of the line arrangement and ring arrangement of magnetic balls.

Key words： uniform magnetization; permanent magnet ball; magnetic field; magnetic charge
