Abstract

PURPOSE:To converge the magnetic flux to the center section effectively and completely and improve the output by arranging a ring-shaped spacer made of a superconducting material coaxially with pole pieces between the pole pieces and forming the inner diameter of the spacer smaller than the inner diameter of the pole piece. CONSTITUTION:A spacer 4 is formed in a ring shape with a ceramic superconductive material having the composition of YBa2Cu3Ox, for example, and coaxially arranged between pole pieces 3, 3. The inner diameter d2 of the spacer 4 is formed smaller than the inner diameter d1 of the pole piece. Since the spacer 4 is formed with the superconductive material with complete diamagnetism between the pole pieces 3, 3, no magnetic flux can penetrate. The magnetic flux is thereby detoured to the center section of the pole piece 3, the leakage magnetic flux is prevented, and the strength of the center mag netic field can be further increased.
