Air Core Transformer Working

Energy is also transported from one circuit to another with air core transformers. With air core transformers, two cable wire-like coils referred to as windings are enfolded onto some form of core substance.

In most circumstances, the wire coils are wound onto a rectangular cardboard-like structure which, in fact, the core substance is air resulting in the transformer being referred to as an air core transformer. In addition, with air core transformers, "all" of the current (electrical energy) is considered to be an exciting or electrifying current, and the current stimulates or induces a secondary voltage that is comparative to a mutual inductance or shared stimulation of transported energy.

A functioning air core transformer can be created easily by simply placing the windings very close to one another. With many air core transformers the coils are wound on a core substance created with material that has superior magnetic permeability. This high magnetic material within the core substance causes the magnetic field which is induced by the electrical current in the primary to become intensely stronger and therefore increases the effectiveness of the air core transformer.

As a result there are no power losses and the ratio of primary voltage to secondary voltage is identical to the ratio of the number of turns within the primary winding coil to the number of turns within the secondary winding coil.
