A calibratable magnetic field sensor (100) for detecting a first spatial component and a second spatial component (By, Bz; Bx, By) of a magnetic field at a reference point (101), wherein the magnetic field has a first measurement field component and a second measurement field component (BMy, BMz; BMX, BMy) and/or a first calibration field component and a second calibration field component (BKy, BKz; BRX, BKy). The magnetic field sensor (100) comprises a first sensor element arrangement (104; 106), which has at least one first sensor element and one second sensor element (104a, 104b; 106a, 106b), for detecting the first magnetic field component (By; Bx), which has a first measurement field component (BMy; BMX) and/or a first calibration field component (BKy; BRX), with respect to a first spatial axis (y; x) at the reference point (101). The magnetic field sensor (100) also comprises a second sensor element arrangement (102; 104) for detecting the second magnetic field component (Bz; By), which has a second measurement field component (BMz; BMy) and/or a second calibration field component (BKz; BKy), with respect to a second spatial axis (z; y) at the reference point (101). The magnetic field sensor (100) also has an exciter line (108) which is arranged with respect to the first sensor element arrangement (104; 106) in such a manner that, when a predefined current (Ikl) is injected into the exciter line (108), a pair of different predefined calibration field components, (BKya; BKxa) in the first sensor element (104a; 106a) and (BKyb; BKxb) in the second sensor element (104b; 106b), is produced in the first sensor element arrangement (104; 106) with respect to the first spatial axis (y; x), wherein the two spatial axes (y, z; x, z; x, y) run along linearly independent position vectors.
