Abstract
A mobile body moves along a magnetic pole path. The magnetic pole path includes a first magnetic pole section and a second magnetic pole section. The mobile body includes a detector, a rate changing unit, and a position specifying unit. The detector detects a phase angle in accordance with a magnetic flux of the magnetic pole path. The rate changing unit changes a position conversion rate obtained by associating a phase angle of the magnetic pole path with a position of the magnetic pole path based on the phase angle detected by the detector. The position specifying unit specifies a position of the mobile body along the magnetic pole path based on the phase angle detected by the detector and the position conversion rate changed by the rate changing unit.
