Analysis of Electromagnetic Thermal Coupled Field in Pulsed Magnet With Finite Element Method

Pulsed magnet bears the effect of electro-magnetic, thermal and structural fields. During the design procedure, lots of factors have to be taken into account, which makes the analysis extremely complicated. The model of the coupled magnetic and thermal analysis in a 70 T prototype pulsed magnet was established with commercial finite element analysis software ANSYS. The magnetic field and temperature distribution were calculated. Based on the analysis, the performance of the pulsed magnet was optimized. Experimental results show that 70 T magnetic field is achieved with the pulsed magnet.
