Detailed explanation-1: -An electromagnet is a coil of wire wrapped around an iron core. Electromagnet is a type of magnet in which a magnetic field is generated by an electric current. Current passing through the wire creates a magnetic field which is concentrated at the centre of the coil.
Detailed explanation-2: -An electromagnet is a solenoid wrapped around a bar of iron or other ferromagnetic material. A solenoid is a coil of wire with electric current flowing through it. This gives the coil north and south magnetic poles and a magnetic field.
Detailed explanation-3: -An electro magnet is a temporary magnet made by winding wire around an iron core. When current flows in the coil the iron becomes a magnet, and when the current is turned off it looses it’s magnetic properties.
Detailed explanation-4: -An electromagnet is a temporary magnet created by coiling a wire around a metal core, and passing a current through the wire.
Detailed explanation-5: -An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil (spiral or helix).
