ABSTRACT:
A magnetic guide apparatus includes at least two gap sensors which are disposed with a predetermined interval in a direction of movement of a moving body, and detect a gap between a magnet unit and a guide rail, a signal correction unit which determines variation amounts of detection signals which are output from the gap sensors, relatively varies weight coefficients for the respective detection signals on the basis of the variation amounts, and outputs, as a signal for magnetic control, a signal which is obtained by adding the detection signals which are multiplied by the weight coefficients, and a control unit which controls the magnetic force of the magnet unit on the basis of the signal for magnetic control, which is output from the signal correction unit.
