Abstract : The case of a rigid conducting sphere that travels with uniform velocity relative to a two-dimensional, primarily transverse magnetic field with sinusoidal variation in space and time is analyzed to determine the electro-mechanical characteristics of the interaction. An exact solution is not tractable by standard techniques, hence, two approximate methods are used. In one, the force of electromagnetic origin is approximated by one of its components and in the other, a lumped parameter model is constructed. It is shown that approximating the force by one of its components yields favorable results in the case of the cylinder and sphere provided the wavelength of the applied field is much greater than the diameter of the body. It is also shown that lumped parameter modeling is a feasible and practical method for obtaining solutions to a certain class of problems which are not amenable to exact analysis. The study is concluded with a determination of the condition under which two spheres are electromagnetically independent so that the results for a distribution of spheres may be obtained by superposition of the results for a single sphere.
