A magnetometer assembly (22) for a torque transducer (10) includes inner and outer coils (34,38,36,40) wrapped and supported on a bobbin assembly (22). The bobbin assembly (22) includes upper and lower axial portions (21,23) divided by a middle flange (28). The middle flange (28) includes a plurality of notches (32) that are disposed equal angularly about an axis (18). A plurality of corresponding magnetic strips (42) extend axially through each of the notches (32) and through the entire length of the magnetometer assembly (22). The magnetic strips (42) are disposed between an inner and outer coil assembly (34,38,36,40) and becomes saturated in the presence of a magnetic field. Divergent magnetic fields created by torque applied to a torque transducer element (12) disposed within the magnetometer assembly (22) and detected and measured to provide an indication of applied torque.
