Claim 16:
17. A multi-degrees of freedom magnetic levitating system comprising:
an actuator comprising at least two iron cores, each iron core including a pole extending in a first direction parallel to a direction of gravity, a permanent magnet disposed between the at least two iron cores so as to generate a magnetic field along a shape of a combination of the at least two iron cores arranged so as to be adjacent to each other in a direction not parallel to the first direction, and a winding wound around the pole of each of the at least two iron cores; and
a sensor module including at least two optical-fiber sensors, wherein each of the at least two optical-fiber sensors is disposed under each winding of the actuator,
wherein the at least two optical-fiber sensors measure a position of a magnetically-levitated body,
wherein the system is configured to apply a current to each winding to control the position of the magnetically-levitated body, based on the measured position of the magnetically-levitated body.
