Abstract
A magnetic field generation apparatus includes a main coil and a variable-current correction coil. The main coil is formed by winding a ReBCO-based superconductive wire rod and generates a magnetic field in a measurement space. The variable-current correction coil is variable in a value of a current, coaxial with the main coil and disposed inside the main coil, and generates a magnetic field which corrects a uniformity of the magnetic field generated by the main coil.
