Beschreibung
Zusammenfassung:	A magnetic field generating apparatus which generates a cusped magnetic field on an electrode includes a magnet mechanism which is attached to the electrode and includes a plurality of magnets held on a holding plate, and a rotation mechanism which rotates the holding plate. The plurality of magnets (61) are regularly arrayed to be point-symmetrical about a specific point. The specific point is at a position shifted from the center of rotation of the holding plate by the rotation mechanism.
