Abstract
A magnet includes one or more polar regions each having an arc shape and arranged in a circumferential direction. A magnetic focus center of each polar region is different from a center of an inner diameter of the one or more polar regions. A value obtained by dividing (i) d, a distance from a straight line connecting ends of a first magnetic center line of the one or more polar regions to a center of the first magnetic center line, by (ii) d, a distance from a straight line connecting ends of a second magnetic center line of the one or more polar regions to a center of the second magnetic center line, satisfies certain values based on a number of the polar regions. dis determined based on the one or more polar regions having a magnetic focus center that corresponds to the center of the inner diameter.
