Abstract
A transport device and a transport method efficiently increase a thrust to suppress power consumption. The transport device has a first magnetic body on a side of a to-be-transported object, a magnetic circuit with a core consisting of a second magnetic body, and a winding wound around an outside of the core, and a drive circuit supplying a current to the winding of the magnetic circuit. The magnetic circuit has first and second magnetic circuits, and in a case where the first magnetic body is located on a side of the second magnetic circuit relative to a first predetermined position between the first magnetic circuit and the second magnetic circuit, the drive circuit supplies a current to a winding of the first magnetic circuit in such a manner to cause an electromagnetic repulsive force to be generated between the first magnetic body and the first magnetic circuit.
