摘要

The electromagnetic force of electromagnetic materials owns the attractive and the repulsive components, which can respectively be introduced from the Lorentz force and the Kelvin force formula. In the harmonic fields, the attractive and the repulsive components both own the DC and the AC components, which can cancel out with each other to reduce the total force. The contributions or influences of the frequency, the magnetic permeability and the electric conductivity of the material to the attractive and the repulsive force in time-varying fields are analyzed and simulated by the numerical simulations of FEM. The electromagnetic forces of ferromagnetic material sheet with another conductor sheet together are also simulated. The result shows that the total time average electromagnetic force could be reduced greatly in some cases, which is useful to reduce the vibration of the materials.
