<p>There is provided a magnetic field sensing probe (100) comprising a ferromagnetic material (120), a sense coil (135), and electromagnetic shielding (110, 115). The ferromagnetic material comprises a base portion (121), a coil portion (125) extending from the base portion, and at least one flux portion (122, 123) extending from the base portion. The sense coil (135) comprises sense coil windings that encircle the coil portion (125) about an axis (136). The electromagnetic shielding comprises an electrically conductive can (110) within which the ferromagnetic material (120) and sense coil (135) are housed, the electrically conductive can having sides (113), a base (112) at a first end, and an opening (114) at a second end opposite the first end. The sense coil is rotationally orientated with the axis (136) of the sense coil windings directed through the second end. There is also provided a magnetic field sensing apparatus (500) comprising the magnetic field sensing probe (100) and a signal processing circuit (510)..</p> |
