# Only one pole in a horseshoe magnet

Is it possible for a horseshoe magnet to have only one pole? For example, if i take a horseshoe shaped iron core and wind a conductor such that both the ends of the horseshoe have current flowing in the clockwise direction, then both ends are south poles. Is this possible? In that case how are the domains aligned?

You create the equivalent of two permanent magnets with equal poles held together: The fields will largely cancel each other and you get a complex and weak sum of the two fields.

You cannot create magnetic monopoles that way. While these might exist as elementary particles, no magnetic monopole has ever been found - if they exist at all, they must be incredibly rare.

As mfb pointed out, you are connecting the two coils in series opposition. This way, you are reducing the net magnetic field inside the magnet by effectively reducing the inductance of the coil (look up series-aiding and series-opposing coil connections).
