Claim:
1. A sensor package comprising: a magnetic field sensor, said magnetic field sensor including an in-plane sense element and a flux guide configured to direct a magnetic field oriented perpendicular to a plane of said magnetic field sensor into said plane; a current carrying structure positioned proximate to said flux guide, said current carrying structure including a continuous coil having multiple substantially parallel conductive segments connected by additional conductive segments oriented perpendicular to said parallel conductive segments to form a continuous series of loops, wherein said parallel conductive segments of said continuous coil are arranged adjacent to one another, and said parallel conductive segments are oriented substantially perpendicular to a length of said flux guide; and circuitry coupled to said current carrying structure, said circuitry being configured to provide an electric current to said continuous coil such that said electric current flows through each of said parallel conductive segments, wherein said continuous coil includes a subset of adjacent ones of said parallel conductive segments for which said electric current flows in the same direction, said subset of adjacent ones of said parallel conductive segments are in proximity to said flux guide, said electric current generates a magnetic field, and said magnetic field is applied to said flux guide to recondition a magnetic polarization of said flux guide.
