Abstract

Various exemplary embodiments relate to a magnetometer device to measure oscillation frequency, including a feedthrough loop including an amplifier and a voltage bias connected to a first input of a metallic membrane; a membrane ground connected to a membrane output; a fixed plate including a first fixed plate output connected to a second input of the amplifier, wherein the fixed plate is physically separated from the metallic membrane but connected to the metallic membrane by a Lorentz force, and where the physical separation differs due to an angle of a magnetic field relative to a direction of a current; a second fixed plate output sensitive to the Lorentz force; and a circuit connected to the second fixed plate output to calculate an angle of the magnetic force based upon the Lorentz force.
