The present invention relates to a method for contactless measurement of a relative position of a magnetic field source, which produces a magnetic field and a magnetic field sensor in relation to each other. The present invention further relates to a corresponding displacement sensor. According to the present invention, the magnetic field sensor detects at least two spatial components (Bz, By) of the magnetic field and a position signal is produced from the measured components. The method comprises the following steps of calculating the position signal based on a quotient of the two magnetic field components; and correcting, before the quotient is calculated, the magnetic field component, which extends in a movement direction between the magnetic field source and the magnetic field sensor.
