A micro magnetic device having a body defining at least part of an
enclosed chamber, the body comprising a first sidewall and a second
sidewall. A pole comprising a soft magnetic material is within the
chamber and an electrically conductive coil is positioned around the
pole. A diaphragm is connected to the first sidewall and a permanent
dipole magnet is connected to the second sidewall at a first end and to
the diaphragm at a second end. The dipole magnet is offset centrally from
the pole. The diaphragm may also be offset centrally from the first pole.
The micro magnetic device may be made by MEMS or thin film techniques.
