The numerical simulation of reinforced high magnetic field coil

Abstract

The performance of a 40 T pulsed magnet is simulated with finite element method. ANSYS software for numerical simulation of magnetic field and mechanical deformation in pulsed magnet was applied. Due to construction symmetry the 2-D model of multilayer reinforced pulsed magnet was realized. The coil was wound with standard copper wire. The results show that the finite element technique is useful tool for the design of pulsed coil. Analysing the distribution of magnetic forces and layers displacement it was found that high mechanical overloads took place in copper winding but magnet construction had an acceptable mechanical stability due to interlayer reinforcement.
