Poles of a Magnet
Understanding that every magnet has two poles - north and south.
Core concept
If a bar magnet is cut in half, each half will form a new, complete magnet with its own north and south pole — magnetic poles cannot exist alone. This is different from electric charges, where positive and negative charges can be separated. The poles of a magnet can be identified using a compass: a compass needle's north-seeking end will point away from a magnet's north pole and towards its south pole, since it is itself a small magnet responding to the larger magnet's field.
