Question

For making a temporary magnet, which material will you select: soft iron or steel?

Answer 1

Explanation:

1. For making a temporary magnet, we will select soft iron.
2. Iron gets magnetized faster and also loses its magnetism as soon as the inducing magnet is removed.
3. Hence soft iron is said to have high susceptibility but low retentivity.
4. This property of soft iron is very useful in making temporary electromagnets where we need strong but temporary magnets.
