While cross-linking the first and second phase windings of the amount of magnetic flux φm, the magnetic flux as the main flux.

In addition to the chain, a winding 2 times the volume of magnetic flux is φ m, the magnetic flux as magnetic flux.

The transformer may divide into according to the use: The distribution transformer, the power transformer, all seal the transformer, the combined transformer, the dry transformer, the oil bath type transformer, the single phase transformer, the electric stove transformer, the rectification transform

While chain, secondary windings for the amount of magnetic flux φ m, the magnetic flux is called the primary flux.
