(C) An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.To create a strong electromagnet, the core material must have high magnetic permeability and low retentivity.$soft \ iron$ is an ideal material for this purpose because it can be easily magnetized and demagnetized.When the current is switched on, it becomes a strong magnet, and when the current is switched off, it loses its magnetism almost instantly.Therefore, $soft \ iron$ is used for the core of a strong electromagnet.

The material of the core of a strong electromagnet is:
