Answer 2

Answer:

Explanation

In order to make a magnet following steps should be taken:

• A bar magnet and an iron bar is taken.

• Without lifting, move the bar magnet from one end of the iron bar to the other end.

• After reaching the other end, the bar magnet is lifted, and the same process is repeated by stroking the iron bar about 30-40 times.

• Now, paper clips or iron fillings are brought near the iron bar. They cling to the end of the bar.

Hence, the iron bar becomes a magnet.
