We propose a linear scheme for the numerical solution of the eddy-current equation coupled with the Landau{Lifshitz{Gilbert equation where the e ective eld contains some general energy including anisotropy elds and applied elds. At each time-step, our suggested algorithm solves successively two linear systems, one for the magnetization eld and another one for the magnetic eld. Convergence to the weak solution is proved. Numerical experiments with a micromagnetic benchmark problem underline the performance

of the proposed algorithm.
