Answer:
We can convert an iron strip into a bar magnet by the following method:
(i) Take an iron strip.
(ii) Place it on the table.
(iii) Now, take a bar magnet and place one of its poles near one edge or the bar of iron.
(iv) Without lifting the bar magnet, move it along the length of iron strip till we reach the other end.
(v) Now, lift the magnet and bring the pole (the same pole we started with) to the same point of the iron strip from which we began.
(vi) Now, move the magnet again along the iron bar in the same direction as we did before.
(vii) Repeat this process about 30-40times.
(viii) Bring a pin or some iron fillings near the iron strip to check whether it has become a magnet.
If not, continue the process for some more time
Note The pole of the magnet and direction of its movement should not change in this process
