an electromagnet can be made by wrapping wire around which object?

The correct answer is ''nail".

Explanation:

Electromagnet is a temporary magnet. The electromagnet is made by wrapping the coils around the soft iron. Then, pass the current through it. In this way, It will act as a temporary magnet.

As long as the current passes through it it will retain its magnetic property. When the current is not flowing through it then it will lose its magnetism.

Iron is a ferromagnetic material. It will retain the magnetic property as long as the current flows in the electromagnet.

Therefore, an electromagnet can be made by wrapping wire around the nail.
