Magnetic structure for detecting a relative motion between the magnetic structure and a magnetic field sensor
First Claim
1. A magnetic structure for detecting a relative motion between the magnetic structure and a magnetic field sensor, the magnetic structure comprising at least two permanent magnets whereinthe permanent magnets are arranged along a predetermined line at a predetermined distance g from each other,the permanent magnets are magnetized in the direction of the line,adjacent permanent magnets have an opposite direction of magnetization, andthe distance g fulfills the two conditions g≧
- 0.25*lmin and g≦
4*lmax, with the quantity lmin designating a length of the shortest of the permanent magnets as measured along the line and the quantity lmax a length of the longest of the permanent magnets as measured along the line.

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.
