Suspend each of them in the earth’s magnetic field. Change their rest position and record the final direction in which key will rest. Repeat this procedure several times and record the directions. Do this experiment on each of the rods. It is noted that, the magnetized rod will rest in the earths North-south direction each time it is disturbed. The unmagnetised rod rests in random directions.
