According to some embodiments, an apparatus includes a movable portion through which a sensing current is to be conducted. The movable portion might comprise, for example, a beam or plate suspended above a well in a Microelectromechanical System (MEMS) substrate. The apparatus may also include a sensing portion coupled to the movable portion, and the movable portion and/or sensing portion may move in a direction normal to the substrate in response to a magnetic field.
