Claim:
1. A Hall effect sensor with a plurality of Hall effect elements, each of the Hall effect elements comprising: a first contact terminal; a second contact terminal; and a third contact terminal, the first, second and third contact terminals of each Hall effect element being arranged linearly, wherein the plurality of Hall effect elements are electrically connected in series in a closed circuit such that at least three Hall effect elements of the plurality of Hall effect elements have the first contact terminal connected to the third contact terminal of another of the at least three Hall effect elements, such that current flows in a single circular direction through the at least three Hall effect sensors, wherein the second contact terminals of the Hall effect elements are supply voltage connections or Hall voltage pickoffs, wherein the second contact terminal of each Hall effect element is a center contact of the Hall effect element, wherein the Hall effect elements form two pairs, and the Hall effect elements of a first pair of the two pairs each measure a same component of a magnetic field, wherein an operating current is impressed on the series circuit in the two Hall effect elements of the first pair, and wherein a supply voltage is applied to the Hall effect elements of a second pair of the two pairs, wherein the two second contact terminals of the first pair face each other along a first axis and the two second contact terminals of the second pair face each other along a second axis, wherein the first pair of Hall effect elements are arranged along two first substantially parallel lines, and wherein the second pair of Hall effect elements are arranged along two second substantially parallel lines, the two first parallel lines and the two second parallel lines being substantially perpendicular.
