  • Abstract

We propose in this paper an alternating A-0 method for the quasi-magnetostatic eddy current problem by means of finite element approximations. Bounds for continuous and discrete error in finite time are given. And it is verified that provided the time step 7- is sufficiently small, the proposed algorithm yields for finite time T an error of $O(h+\tau^{1/2}$ in the $L^2$ -norm for the magnetic field $H(= \mu^{-1} \nabla \times A)$, where h is the mesh size, $\mu$ the magnetic permeability.
