How does a compass move?
Compasses work so effortlessly because their design allows the magnet to respond freely to Earth’s magnetic field. Earth itself is like a giant magnet that creates its own magnetic field. The north end of a compass is drawn to align with Earth’s magnetic North Pole. … As it does so, the magnetic North Pole moves.
