A remote non-invasive current sensing apparatus for sensing current being carried through a conductor located beneath or on top of a surface. First and second magnetic field sensor elements are placed in operative connection with the surface. There is no requirement to insert the sensor element within the current line by cutting the line or to encircle/enclose the conductor within a coil or other element. The second magnetic field sensor is located a predetermined distance from the first magnetic field sensor. The outputs of the magnetic field sensors are amplified and then provided to a processor which calculates the amplitude of the current in the conductor and the distance of the conductor is from the surface.
