MAGNETIC FIELD GENERATION DEVICE COMPRISING MAGNETIC FIELD VARIATION MECHANISM FOR ARBITRARILY CHANGING MAGNETIC FIELD AT MAGNETIC FIELD GENERATION POSITION, AND MAGNETIC FIELD ADJUSTMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a magnetic field variation mechanism capable of eliminating the need for power and cooling water, of reducing maintenance costs, of resolving troubles caused by power supply and cooling water, of having a simple structure, of being applied to a compound functional magnet and the like with a magnetic field gradient, and of changing a magnetic field drastically and ununiformly.;SOLUTION: A magnetic pole 1 is arranged at the center. A permanent magnet 2 is arranged on both sides of the magnetic pole 1. A magnetic body 3 is arranged outside the permanent magnet 2. An external magnetic body plate 10 is arranged on an opposite side to a magnetic field generation position. The external magnetic body plate 10 is attached to an external magnetic body drive shaft 15 provided on an upper surface of the magnetic body 3, and can be moved in a Y-direction. The generated magnetic field is arbitrarily changed by moving the external magnetic body plate 10 without moving the magnetic pole 1.;COPYRIGHT: (C)2016,JPO&INPIT
