Abstract
PURPOSE: To improve the efficiency of attraction by weakening a magnetic field produced in a predetermined portion without weakening the attraction force for attracting the object to be attracted by making effective use of a character that like polarities of electromagnetic coils repel each other and opposite polarities attra attract each other.
