Abstract

A current sensor for measuring a current in a conductor includes two magnetic field sensors located adjacent to the conductor. The magnetic field sensors are at least two-dimensional magnetic field sensors having two measuring directions, thereby facilitating compensation for an inhomogeneous interference field.
