A method and apparatus for detecting relative movement of two system (S, S2) by using electromagnets induction (B, v, i) on a sensor with a defined magnetic field (Bm) and compensating for the influence of an external interfering magnetic field (Bs). The magnetic field (Bm) is generated in at least two areas (M, M2) with reversed polarity and a conductor arrangement is designed so that an addition induction effect (i, i2) occurs on the conductor and the external interfering field (B2) is corrected by the additive induction effect.
