Description
Measurements were made of the forces experienced by two narrow but relatively long permanent magnets positioned above a moving, electrically conducting surface. The intent was to determine the accuracy of various means of computing these forces. It was found that the behavior at very high speeds can be approximated by using elementary methods and making the assumption that magnetic images are formed in the conductor. At lower speeds, a published formulation that uses Fourier transform techniques is quite reliable for the parameters of the experiments. A commercial computer code that uses a finite-element method of analysis is also in good agreement The results are relevant to the design of high-speed magnetically levitated (maglev) ground transportation vehicles having multiple magnets, where the guideway consists of a continuous-sheet conductor.
