A compass has a magnetic needle that can rotate freely. When a compass is kept at a place, the magnetic needle aligns in a north-south direction. The red arrow of the compass needle is termed as the north pole and the other end as the south pole.
When a magnet is broken into 20 pieces , each piece will act as an independent magnet, so there will be 20 north polies and 20 south poles.
