Abstract
A method and an arrangement for magnetically determining a position using a permanent magnet are described, wherein the vector and local gradient of the magnetic flux density of the permanent magnet are measured using a position sensor, and the position and orientation of the magnetic dipole of the permanent magnet relative to the position sensor are calculated from the measured values. A spherical permanent magnet having homogenous magnetization is used in the method and the arrangement, preventing previously present cross-sensitivity between the position and orientation determination, and allowing measurement without prior calibration.
