Question

Show that a magnet has two poles. What are the properties of the poles of a magnet?

Answer 1

We know that pole is the point where the strength of the magnet is maximum. So more and more iron particles will be attracted at poles of a magnet when we bring a magnet near the iron particles. We will observe the crowdness of particles at the ends of magnet. This indicates the presence of two poles in a magnet. Hence poles are present in a magnet in pair. If a magnet is divided into two parts, each part also possesses a pair of poles.

Two properties of a magnet are: (i) A magnet always has two poles: north pole and south pole. (ii) Like magnetic poles repel each other and unlike magnetic poles attract each other.
