MAGNETIC FIELD CORRECTING APPARATUS

摘要

PURPOSE:To obtain a magnetic field correcting apparatus which prevents variations in magnetic distribution because of external excitation, and does not involve a drop in workability and a risk due to magnetic suction force. CONSTITUTION:Magnetic substances for magnetic field correction purposes 14 and 17 are fixed to first and second mounting plates 13 and 16 by means of an adhesive, respectively. These plates are piled up on fixtures 12 positioned on a case 11 for a magnetic field generation coil by mounting screws.
