Abstract
An integrated magnetometer comprises at least one field sensor unit including a first transducer element for generating, in response to a detected magnetic field, a first electrical output signal. At least one gradient sensor unit of the magnetometer includes at least a pair of second transducer elements which are arranged to detect the magnetic field at two different locations and generate, in response to the detected magnetic field, a second electrical output signal. The first and second transducer elements are formed on a common substrate and are encompassed by a common protective layer and/or housing.
