Question

How can you find out whether a metallic bar is a magnet or not?​

Answer 1

Answer:

Bring one pole of a bar magnet ( say the north pole ) close to both the ends of the substance , one by one . If one end is attracted and the other end is repelled , the given substance is a magnet. If both ends are attracted , the given substance is not a magnet. Repulsion is the true test of magnetization.

Answer 2

if a bar magnet has the property of magnet if like poles of a bar magnet repeal each other and unlike poles of a bar magnet attract each other and all the properties of a magnet will be found in bar magnet then it is a bar magnet
