概要

• 論文の詳細を見る

• The amount of the leakage flux outside the yoke was measured for five kinds of barrel type magnet assemblies with various curvature radii at yoke corners in order to find a suitable yoke shape which provides a stable magnetic field between pole pieces. Th: path length of the leakage flux which was expressed as the product of the magnetic circuit length of yoke and the ratio of the magnetic fields in and outside the yoke, was exponentially increased with increasing curvature radius of an intermediate plane of the yoke. The leakage flux was calculated for various shapes of the yoke using the experimental results.
