Visualization of Eddy Current Distributions for Arbitrarily Shaped Coils Parallel to a Moving Conductor Slab

Abstract: Abstract-To visualize eddy current distribution (ECD) of an arbitrarily shaped coil arranged parallel to a moving conductor slab, an exact theoretical solution is derived using an analytical method based on the double Fourier transform method. The arbitrarily shaped coil is regarded as a plane coil of a single turn, and both DC and AC excitation currents can be applied. Furthermore, ECD charts are obtained when the conductor slab is moving. We calculate some examples with respect to a circular coil, rectangula… Show more

“…It consists of a permanent magnet above six meander line coils and a non-ferromagnetic material represented in an aluminum plate. It is widely known that the Lorentz force has a major contribution in non-ferromagnetic materials, while in ferromagnetic materials, the magnetostrictive force contributes more [15]. Thus, the EMAT transduction mechanism in the aluminum plate is known as the Lorentz force.…”
