Explanation:
A magnet is a piece of object that produces a magnetic field outside itself. A magnet has a north pole and a south pole. Similar poles repel each other, while opposite poles attract each other.
If a magnet of 10cm is broken into 3 pieces, we will have 3 pieces of magnet. Breaking a magnet does not destroy the properties of the magnet. Rather, each piece becomes a full magnet with both north and south poles.
Breaking a 10cm magnet will give us 3 magnets with 3 north and 3 south poles with equal pole strength.
