An efficient three-dimensional (3D) inversion algorithm for recovering magnetic targets when remanence exists

In mineral exploration, the ores with different magnetic susceptibility can be well delineated by physical property inversion of magnetic data. However, further wide applications of the magnetic inversion method have been seriously restricted by the existence of strong remanence and the computation...
