Why do compasses work at all?

• the earth is a magnet with an molten iron core which creates a magnetic field around the earth

• it's magic

• the earth has a large magnet buried in it

The magnetic force

• moves from the positive (north) to the negative (south)

• moves in random waves around the magnet

• moves from the negative (south) to the positive (north)
