Iron core. The use of iron is to help in the proper flowing of current. You can make electromagnet without the iron core also. But it is better to use iron core.The iron core does directly affect the current flow. It's purpose is to concentrate the magnetic flux produced by the current flow in the area outside the wires.
Wire. The wire is very important. The number of turns of wire represents the power of the electromagnet. The wire flow the current creating magnetic field. That will create the poles also.
Flowing current. It is very important part of the electromagnet. The flow of current also represents the power of electromagnet. If there is high flowing current, there is high powered electromagnet.
Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges. Spinning like tops, the electrons circle the nucleus, or core, of an atom.
