Effect of thickness on dipole magnitude and orientation. Effect of thickness of the CM layer on dipole (left) magnitude and (right) orientation computed using a 3D mesh over a period of ~10 s. Over this time period a slow wave appears from the proximal end of the mesh, propagates down the cylinder and disappears from the distal end. The maxima for each problem is denoted by M1 and M2 in (right), with the solid black arrow indicating the direction of the movement of the dipole heads. The ratios show the relative thicknesses of the LM, ICC and CM layers.
