Abstract：The accurate formulae which express component and total magnetic anomalies of uniformly-magnetized polyhedron by using angular coordinate and magnetic pa-rameters are derived from coordinate-turning conversion, Gauss' divergence theorem and Stokes' theorem. Magnetic anomaly estimation results of two 2.5-dimensional theoretical models show that magnetic estimation results obtained by using these formulae are consistent with magnetic results derived from Rasmussen's 2.5-dimensional magnetic anomaly formulae. Rasmussen's formulae may be considered as the special case of 3-D magnetic anomaly formulae in the paper.
