Magnetic field perturbations due to a hole in a conducting wall near a time changing magnetic field
Abstract
Plasma confinement devices frequently employ a conducting wall to confine a pulsed magnetic field. Holes in the wall produce perturbations of the uniform field which can affect the plasma equilibrium and field topology. The magnetic field perturbation around such a hole has been calculated using the quasistatic approximation for various cases by analytic and numerical methods, and has been measured for one case experimentally. Simple analytic approximations are presented. The perturbations near a conducting interface are found to be of a much longer range than would be true for fields of the same symmetry in free space.
