3. THE INDUCTION PHENOMENON The electromagnetic induction is the phenomenon that originates the production of an electromotive force in a way or body exposed to a magnetic changeable field, or in a mobile way with regard to a magnetic static field. When the mentioned body is a conductor, an induced current is produced. This phenomenon was discovered by Michael Faraday who expressed it indicating that the magnitude of the induced voltage is proportional to the variation of the magnetic flux (Faraday's Law).

4. FERRITE HONEYCOMB COIL:

5. DEFINITION: The honeycomb coils is wounded in a crisscross manner to reduce distributed capacitance. It is used in the circuits tuners radio in the ranges of medium and long waves, thanks to the shape of the winding are achieved inductive high values in low volume.

6. TOROIDAL CORE COIL.

7. DEFINITION The coils of toroidal core are characterized to generate flow that does not disperse towards the exterior, because of its form it is created a closed magnetic flux, providing them with a great performance and precision.
