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.
