Main Question or Discussion Point

What happens when you try to create a ring shaped magnet with a circular magnetisation.
e.g. you take an unmagnetised steel ring, wind some copper wire around it, turn on the current for a few seconds and then remove the wire. Afterwards there should be a circular magnetic field inside the ring right? Will there be any field outside?
