Abstract
A magnetic structure for detecting a relative motion between the magnetic structure and a magnetic field sensor comprises at least two permanent magnets. The permanent magnets are arranged along a predetermined line which for example is a straight or circular line at a predetermined distance g from each other. The permanent magnets are magnetized in the direction of the line, adjacent permanent magnets having an opposite direction of magnetization.
