Solution

An electromagnet is a temporary magnet. Its magnetic properties are only for the duration of the current passing through it. So, an electromagnet can be switched on or switched off as desired.

The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current.
