Abstract
The solution of the electromagnetic field in any electromagnetic device is best appreciated if expressed in terms of the terminal characteristics of the device, namely forces. In this paper expressions for force calculations are derived from the numerical field solutions in terms of \bar{T} -the electric vector potential and Omega(Ω)-the magnetic scalar potential. The volume integral method is used with the finite element technique as a differential numerical approach. The technique was tested to predict the levitating force acting on a E core plate levitator and the results were in good agreement with the experimental measured values.
