Abstract
A magnet chuck includes, for example, four permanent magnets of a first permanent magnet through a fourth permanent magnet, serving as an attracting and retaining member for attracting and retaining a workpiece. In the first permanent magnet and the third permanent magnet, the magnetic polarity of a workpiece magnetic attracting surface facing the workpiece is of an N-polarity. On the other hand, in the second permanent magnet and the fourth permanent magnet, the magnetic polarity of a workpiece magnetic attracting surface is of an S-polarity. More specifically, in this case, combinations of the N-pole and the S-pole on the workpiece magnet attracting surface are formed in two pairs, and the N-pole and the S-pole, which are of different polarities, are adjacent to one another.
