Question
You are given an iron strip. How will you make it into a magnet?
Solution
The ‘Touch and stroke’ method can be used to make an iron strip into a magnet. For this, a bar magnet is required. The bar magnet is moved along the length of the iron strip starting from one end to the other end (as shown in the given figure).
Then, the bar magnet is lifted from the other end and brought to the starting point again with the same pole of the bar magnet. On repeating the process at least 30 to 40 times, the iron strip will become a bar magnet with two poles.
