Abstract
In this paper, we propose an optimization method for magnetic shielding. Our main purpose is the weight reduction of shield material. Assuming that the permeability of shield material is infinite, we simplify the magnetic shielding problem. Under this assumption, we design optimal passage for magnetic flux through the shield. We apply this method to designing the magnetic shielding for Maglev and show the effectiveness of this method by experimental and numerical data
