This work presents a method of modelling eddy-currents excited in low conducting areas by low frequency magnetic field. The authors suggest a new method for simulation of the phenomenon on the basis of a popular model, using the electric scalar potential. Proposed model uses the condition for continuity of the current density J on the material non-homogeneity borders. The correctness of the proposed model was verified on simple geometric bodies, because in such a situation there is a possibility to obtain analytic solution. The numerical experiment proves an advantage of this method for computationally exhaustive large biomedical models, built on the basis of MRI scans.
