Eddy Current Losses in Conducting Slabs

This paper considers the problem of calculating the eddy current losses in a rectangular conducting slab in a magnetic field which would be uniform if the slab were not present. The length axis is perpendicular to the uniform field, but there may be an angular displacement´ about this axis. A rigorous numerical solution is obtained for an infinite length slab. An approximate correction is given for finite length. The results are presented in the form of a simple formula, and two curves of correction factors. The methods used are generally applicable to eddy current problems.
