The invention relates to a magnetic field sensor (1) having an NV diamond (2), an excitation light source (3), which is designed to emit an excitation beam (4) for exciting electronic states of the NV diamond (2) and which is arranged such that the excitation beam (4) emitted thereby can generate an electric field within the NV diamond (2), a detector (5), which is arranged and designed to detect fluorescence radiation which the NV diamond (2) can emit as a result of irradiation with the excitation radiation (4), a microwave structure (6), which is arranged and designed to generate a microwave field within the NV diamond (2) in order to manipulate spin states of the NV diamond (2), a magnetic field generating device (7), which is designed to generate an internal, static magnetic field within the NV diamond (2) and which comprises at least one permanent magnet (8), and a hood (10) and a base plate (11), which are arranged such that they form a closed chamber (12). The NV diamond (2), the excitation light source (3), the detector (5) and the microwave structure (6) are arranged within the closed chamber (12). The hood (10) has at least one recess (13) for receiving the at least one permanent magnet (8, 9).
