MAGNETIC FIELD CORRECTION DEVICE

摘要

PURPOSE:To prevent the motion of magnetic substances for magnetic field correction purposes within a non-magnetic tube in a magnetic field correction device which corrects a magnetic field by adjusting the quantity of magnetic material of the magnetic substances inserted in the non-magnetic tube. CONSTITUTION:Magnetic substances 6 for magnetic field correction purposes are fixed within a non-magnetic tube 7 by pouring non-magnetic members 14 through each of inlets 12 and 13 to fill the inside of the non-magnetic tube 7.
