Abstract
The circuitry and structure of a levitated ball inclinometer are disclosed. A ferromagnetic ball is centerized between pairs of electromagnets by electromagnetic forces of magnitudes sufficient to offset the gravitational forces imposed on the ball. The electric currents required are therefore proportional to the forces and can be used as measurements to determine inclination.
