Abstract: A system may include a magnet fixed to a rotatable object. The rotatable object may be portioned to concentrically rotate about an axis. The system may also include a magnetic angle sensor configured to determine a rotation angle of the rotatable object based on a rotating magnetic field produced by the magnet and sensed by the magnetic angle sensor. The rotating magnetic field may have a radial component and a tangential component, and the magnetic angle sensor may be positioned at a sensor position having a non-zero radial distance from the axis. At the sensor position, an amplitude of the radial component may substantially match an amplitude of the tangential component, or the radial component and the tangential component may share a substantially same gradient magnitude.
