Computation of land mine signatures, as recorded by metal detectors, requires much effort regarding the discretization of the detector coil and the much smaller metal part of the land mine. A domain decomposition method enables a finer discretization for certain areas. By using the Lagrange multipliers approach, the coarse and fine meshed domains are solved at the same time with only one system of equations. In this paper, this method is presented for the magneto-quasi-static application of a metal detector used as a mine searching device
