Beschreibung
Zusammenfassung:	A sensing system and a method for sensing position include a first magnetic track comprising a first number of multipoles for generating a magnetic field solidarily fixed to a second magnetic track for generating a magnetic field and a second sensor for sensing magnetic field, forming a magnetic structure. At least two sensors are included. The first sensor is positioned proximal to the first magnetic track, closer to the first magnetic track than to the second magnetic track. The second sensor is positioned proximal to the second magnetic track. The distance between the first sensor and the second magnetic track is larger than the distance between the second sensor and the second magnetic track. The magnetic flux density generated by the first and second magnetic tracks follow a ratio of two or more.
