Embodiments relate to current difference sensors, systems and methods. In an embodiment, a current difference sensor includes first and second conductors arranged relative to one another such that when a first current flows through the first conductor and a second current, equal to the first current, flows through the second conductor, a first magnetic field induced in the first conductor and a second magnetic field induced in the second conductor cancel each other at a first position and a second position; and first and second magnetic field sensing elements arranged at the first and second positions, respectively. |
