This paper proposes a formulation for magnetomotive force (MMF) employing the magnetic currents. Our formulation introduces the classical MMF into the modern magnetic field computation. The rotation of electric field represents the external magnetic field due to impressed voltage. We demonstrate a magnetic field computation of toroidal inductors by finite elements. Comparison with the computed result using the Biot-Savart law verifies our formulation. It is also verified by the experiments on the air- and magnet-core inductors.
