When a permanent magnet is cut half what will be the result?

• Two single pole magnets, one with a north pole and one with a south pole.

• Two dipole magnets, each with a north and south pole

• The piece of metal will lose it magnetism

• Two single pole magnets, each of the magnets only having north poles

• It depends where you are on the earth when you cut the magnet
