Question

State two ways of magnetizing an iron piece.

Answer 1

The two ways of magnetizing an iron piece are:
1. Magnetic induction method: Take a long iron nail and test it for magnetic properties by bringing near theMagnetic substances. You will see nail does not attract the magnetic substances. Now bring near a pole of a bar magnet to the head of the nail. Now bring the iron paper clips near the pointed end of the nail, you will observe that the iron paperclips now get attracted towards the nail. This is because iron nail has become a magnet. Now take the bar magnet away from the Iron nail, paper clips fall off. This magnetism is temporary.
2. Single touch method: Take a demagnetized piece of iron. Piace It on a table surface. Take a magnet and select its one pole. Now mb it with the selected pole on the iron in one direction for several times. After some time, the iron piece turns into a magnet.
