One knows that electromagnetic coils which are known to be magnetic coilsare used to make inductance in any circuit. The entire construction is based on the electromagnetic cire and the winding that make the electromagnet. Each of the loops of the wire is called a turn. It takes a number of turns to make a coil.
The main use of the coils is in electric devices. The first of these is the transformer. This has at least two coils and the direction of flow of current will determine whether it is a step-up or a step down transformer. Energy is moved from one coil to the other without any physical movement through inductance.
Coils are also present in motors. The electric energy is converted to mechanical movement through the use of magnetic fields. Motors are used for pumping water, air and also in the ceiling fans. It is used in many applications where there is a need for a spray of paint or air.
The generator is an electric device that is used by man. The working principles of a generator and the motor are exactly opposed to each other. In these generators electric power is produced by converting mechanical energy. Hydroelectric power is thus produced. Wind power and energy from waves are green energy resources since they are non-polluting, and they are renewable.
One could easily make the electromagnet. All that one requires is the metal core and the windings that are wound round the core. The iron cores could be something large like an iron bar or something small like an iron nail. If one does not use any metal but rather uses air for constructing the core, the electromagnet will be weak. Some applications use only a weak magnet and for those who want a strong one, they should choose a nail or an iron piece.
Now turn the single stranded wire round the bar so that all but the ends of the conductor are coiled up around the cire. By making them more closely packed you can get a strong magnet. It is advisable to tape or use adhesive to stick these to the cire. Strip the ends of the wire so that the bare conductor is seen.
Now it is time to attach the wire ends to the battery power source. The transformation of such a metal piece into a magnet is completed. The metal objects will now be found to be attracted to the magnetic cire. For making illusions, one could hide the magnet behind some screen or paper and move it slowly using an assistant. The metal objects will be seen to move on their own.
Magnetic coils thus are really the most significant thing in our lives Mtoday. More than half of the electric devices use these to run the devices. One has seen how merely changing the straight wire to a round one has given it the strength to power an electromagnet. Living standards and comfort factor of man has improved because of these wonderful innovations. It is really something we ought to be grateful for.
