Abstract
The magnetic charge distribution of some simplest systems (one dimensional system of five magnetic charges, one dimensional system of seven charges, one dimensional square system of thirteen charges and two dimensional rectangle system of seventeen charges) was calculated according to Coulombs law of magnetism. And then the general method and practical move to solve the problem of magnetic charges distribution in the region of arbitrarily shape on the plane were obtained. It is therefore proved that the problem of magnetic charges distribution in arbitrarily-shaped region on a plane might be solved by magnetic dipole method theoretically.
