A linear transporter includes: a transport path including a stator; multiple transport bodies that move along the transport path; a magnetizer that is installed on each of the transport bodies and generates a magnetic field for use in position detection; a magnetic detection element that is installed on the transport path and detects the magnetic field; a calculator that calculates the position of each of the transport bodies on the basis of the magnetic field detected by the magnetic detection element; and a correction value storage that stores a correction value set, which is a combination of correction values for correcting the position of each of the transport bodies. The magnetizer includes a magnet in which magnetic poles of different polarities are arranged alternately along a moving direction of the transport bodies.

A rotation speed detector includes: a base material to be attached to a rotating body; a first magnetic pole having an arcuate strip shape and provided on the base material; a second magnetic pole having an arcuate strip shape and provided on the base material; and a power generation element including a magnetic wire configured to cause a large Barkhausen effect, and a pickup coil. The power generation element is arranged to face the first magnetic pole and the second magnetic pole so that a longitudinal direction of the magnetic wire is provided along a radial direction of the first magnetic pole and the second magnetic pole. A non-magnetic gap is provided between the first magnetic pole and the second magnetic pole.

A power generation element includes a magnetic member that produces a large Barkhausen effect and magnetism collection members including an insertion part having the magnetic member inserted therethrough. The magnetism collection member includes a first component on an opposite side of a boundary plane to a magnetic field generation unit and a second component on the same side of the boundary plane as the magnetic field generation unit, the boundary plane passing through a center of an imaginary circle inscribed in the insertion part and having a diameter equal to a length of the insertion part in a third direction perpendicular to first and second directions, the first direction is a direction of the insertion of the magnetic member, and the second direction is a direction in which the magnetic field generation unit is disposed. A volume of the second component is larger than a volume of the first component.
