Circular magnetised magnet?

  1. Feb 14, 2012 #1
    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?

    Try googling "magnetic keepers".
