Detailed explanation-1: -So, A magnet which operates only when electric current flows through its insulated copper coil is called electromagnet.

Detailed explanation-2: -An electromagnetic coil, also known as an electric coil or inductor, is an electrical conductor containing a set of conductive wires wrapped around a specified shape and size. This can be a self-supporting (air core) design or include a specified core (ie. iron, ferrite) .

Detailed explanation-3: -Electromagnets are made of coils of wire with electricity passing through them. Moving charges create magnetic fields, so when the coils of wire in an electromagnet have an electric current passing through them, the coils behave like a magnet.

Detailed explanation-4: -Expert-Verified Answer. An electromagnet is referred to as a transitory magnet because it is made up of insulated copper wire wrapped around soft iron. When current flows through it, iron gets magnetic qualities; however, when the current is turned off, there is no current flow, and iron loses its magnetic properties.

Detailed explanation-5: -Copper is used in these electromagnets as coiled wire because it has a low electrical resistance i.e., it is easy for the current to flow through it. Also, a copper wire can be easily shaped to make a coil. Q.
