Simulation of the electromagnetic field for the moving magnet

When the magnet is moving compared to the around space, the moving magnet is sure to lead the alteration around the magnetic field, thus irrigating the electrical field. Maxwell is widely used in computing electromagnetic field and necessary for calculating electromagnetic field. The finite element method plays an important role in simulating for electromagnetic field. On the foundation of Maxwell equations, the paper derived the theory model applying to the electromagnetic field of moving magnet. The simulation is carried out by the finite element method software ANSYS.
