MAGNETIC FIELD GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a magnetic field generator capable of heightening uniformity of the magnetic field, and suppressing enlargement of the whole device.SOLUTION: A current variable correction coil 4 for generating a magnetic field for correcting uniformity of a magnetic field generated by a main coil 2 formed by winding ReBCO-based superconducting wire is provided inside the main coil 2. The magnetic field generated by the current variable correction coil 4 is hardly affected by a shield current flowing in a superconducting layer of the ReBCO-based superconducting wire.
