Question

How will you experimentally show that there are two regions in a magnet where its magnetic strength is concentracted?... ​

Answer 1

Magnetic strength of a magnet is concentrated at the two regions namely the poles of the magnet.
To show this,

take a bar magnet and roll it up in a sheet of iron filings. 

When we lift the bar magnet, we observe that the iron filings do not stick uniformly over its length rather, the iron filings cling to the two ends of the magnet. There are however a few in between but none in the centre of the magnet. From this experiment we can conclude that the magnetic strength is strongest at the two regions which are the two ends of the magnet, known as th
