Question

How will you convert a ‘nail’ into a temporary magnet?

✓

Answer

Spread some steel pins on a wooden board and bring an iron nail near them.
Now, make one of the magnetic poles of the bar magnet touch one end of the iron nail.
Slide it along its length in one direction slowly till the other end is reached.
Repeat the process, as shown in the diagram, 20 to 30 times.
The magnet has to be moved in one direction only.
Avoid the swiping of the magnet back and forth.
Now, bring the iron nail near the steel pins.
The steel pins stick to the iron nail because the nail has become a temporary magnet.
