Abstract

A method of making a cylindrical magnetic circuit which is able to prevent deformation of a cylindrical yoke for holding two or more magnets without increasing the thickness of the yoke more than required, A method of producing a cylindrical magnetic circuit () for generating a magnetic field in a space inside of plural annularly placed magnets (), including: a cylindrical yoke () which is placed radially outside the magnets () and is fixed to the magnets directly or via an intermediate member or substance; and at least one nonmagnetic member () existing between pairs of circumferentially adjacent magnets.
