BENCHMARK PROBLEM 3 (THE BATH PLATE) Available to Purchase

Benchmark Problem 3 of the International Workshops for Eddy Current Code Comparison is an aluminum plate with two holes, the Bath Plate. Currents are induced by a coil carrying time harmonic currents of 50 or 200 Hz. Results from seven groups, using seven different computer codes, are compared with experimental measurements. Different methods treated the holes in very different ways, but all produced generally acceptable results. The good results of the two methods that treated the conductor as a thin sheet suggest that the problem is basically two‐dimensional.
