Abstract
A sensor head includes a magnetic field generating unit for generating a magnetic field in the test object and a magnetic field measuring unit for measuring a magnetic field change in the test object. The magnetic field generating unit includes at least one excitation coil having a plurality of excitation coil windings arranged around an excitation coil axis, and the magnetic field measuring unit includes a measuring coil arrangement having a plurality of measuring coils. The radially outermost excitation coil winding is arranged radially outside the measuring coil arrangement, as viewed with respect to the excitation coil axis, so that the measuring coil arrangement is surrounded by at least the radially outermost excitation coil winding, as viewed in axial plan view of the sensor head.
