Maxwell's equations for electromagnetism can not be solved in terms of E and B^<1)>. Therefore, E and B are not available as solution variables. Electromagnetic potenitals of A and φ should be used instead of E and B in computational electromagnetics. In almost every eddy current problem, there exist induced electric charges due to the spatial change of conductivity. Therefore, the algorithm of calculating eddy currents should at the same time calculate the induced electric charges because the eddy current field is not only a magnetic field but also an electric field. In this paper, two formulations using the electromagnetic potentials which calculate both eddy currents and induced electric charges are presented. The numerical experiment can simulate the distribution of the surface charges.
