What happens to the properties of an iron nail when it becomes an induced magnet?

When an iron nail becomes an induced magnet, it temporarily exhibits magnetic properties due to the alignment of its magnetic domains. In its normal state, an iron nail has randomly oriented magnetic domains, which means it does not display any net magnetic behavior. However, when exposed to a magnetic field, these domains can align in the direction of the external field, causing the nail to act like a magnet while in that field.

This induced magnetism is temporary because once the external magnetic field is removed, the magnetic domains return to their original random orientation, and the nail loses its magnetic properties. Therefore, the correct understanding is that the iron nail does not become a permanent magnet or transform into a different element; it only becomes magnetized as long as it is under the influence of an external magnetic field.
