a platform having a first side, a second end opposite the first side, and a fixed support between the first side and second side;
a first magnet attached to a moveable segment of the platform offset from the fixed support and on the first side, the moveable segment of the platform configured to deflect with respect to a polarization axis of the first magnet in response to a magnetic force from an external magnetic field; and
a sensing element configured to measure deflection of the first magnet with respect to the sensing element, wherein the gradiometer directly measures a gradient of the external magnetic field based on the deflection of the first magnet.
