Abstract
A system and a method can use a magnetic field sensor to measure rotation angles of a ferromagnetic object in the form of a screw having screw threads. The magnetic field sensor can use a plurality of correction coefficients to improve an accuracy of the measured rotation angles of the ferromagnetic object. The magnetic field sensor can be disposed to a side of the screw.
