1. A magnetic guiding apparatus for guiding a moving member by attracting a target by electromagnets provided on the moving member, said apparatus comprising:

  • magnetic-flux detection means movable along the target, for detecting a magnetic flux of the target;

    position measuring means for measuring a position of said magnetic-flux detection means; and

    control means responsive to position information from said position measuring means and magnetic-flux information from said magnetic-flux detection means for detecting a position of the magnetic flux at the target, and for performing demagnetization at the detected position of the magnetic flux.
