A modified T-Ω method for computing 3D eddy current problems is proposed in which the exciting current distribution in the field domain is turned into an equivalent magnetized region so that the unknowns of the computation can be reduced as much as possible. With this model an equivalent variational formulation can be derived, and the finite-element method can be used to solve some eddy current problems more efficiently. Sample calculated and test results for 3-D laminated eddy current problems are given to verify the method
