Abstract

The classical Wilson-Wilson experiment in 1913 about the electromagnetic field in a rotating nonconducting cylinder is studied, based on finite-element analysis. Electric and magnetic fields are coupled through motional terms in the constitutive relations. This particular kind of coupling is usually not considered in the existing numerical models. Effects due to the finite axial extension of the cylinder can be conveniently assessed with the help of the finite-element simulation. This should be useful for the correct interpretation of the experimental data.
