Abstract

A new type of magnetization coil was designed to increase the maximum trapped magnetic flux density and the total flux associated with an appropriate trapped magnetic flux density distribution in a high-temperature superconducting bulk magnet. The coil is composed of an inner vortex-type coil wound with an outer solenoid coil. A pulsed current is applied to the inner or the outer coils. Successive applications of pulsed current from both the inner and the outer coils to only the inner coil provide a distribution of trapped magnetic flux density closer to being conical in addition to an increase of the maximum flux density and total integrated flux. The present magnetization technique, the controlled magnetic flux density distribution coil method, is useful for magnetized high-temperature superconducting bulk applications such as in rotating machines, generators and magnetic separation.
