Abstract
A pivoting device such as a MEMS mirror provides improved coupling between a permanent magnet on the device and an adjacent electrical coil that may provide a drive force or position sensing. The improved coupling is obtained by forming a cavity in the coil structure. The cavity receives the permanent magnet such that the spacing between the magnet and the electrical windings or coil is at a minimum.
