Feasibility Study of a Multipole Electromagnet Using a Parallel Iron-Core Structure.

This paper presents a design concept of a multipole electromagnet using a parallel iron-core structure. An electromagnet can be used in many types ofmagnetic study area, such as work on magnetic susceptibility, the Hall effect research, the magnetooptical effect, and in hysteresis measurements. In electromagnets, generally, only a single probe can be used at a time due to the single pole structure, and it is challenging to measure many samples simultaneously. In this paper, a multipole electromagnet is proposed. It has a parallel iron-core structure and a high-temperature superconducting coil, unlike the conventional electromagnet system. The electromagnet with such a structure enables multiple probes to be used simultaneously. To verify the feasibility of the structure, a small-scale multipole electromagnet was designed using commercialized finite element method software. Based on the design results, a parallel iron-core and coil assemblywas fabricated and the performance of the magnet was evaluated. [ABSTRACT FROM AUTHOR]
