'Magnetic North' is so-called to distinguish it from 'True North' -it has nothing whatsoever to do with describing its magnetic polarity. The poles of a magnet and, therefore, a compass needle, are named after the directions in which they point. Since unlike poles attract, the magnetic polarity of Magnetic North must be a south pole.
How can you turn off a magnetic field by a current?
If the magnetic field is caused only by a current, you can turn the current off.If you have another magnetic field, for example due to a permanent magnet, with a current you can create a magnetic field that counters the first one. But that will only work in certain regions in space; you can't cancel such a magnetic field everywhere in space.
