A transformer is a device that transfers electrical energy from one
circuit to another through inductively coupled electrical conductors.
A changing current in the first circuit (the primary) creates a
changing magnetic field; in turn, this magnetic field induces a
changing voltage in the second circuit (the secondary); this is called
mutual induction. By adding a load to the secondary circuit, one can
make current flow in the transformer, thus transferring energy from
one circuit to the other.

Transformers, more than meets the eye.
Transformers, on poles pointed to the sky
Faraday's law of induction states that
instantiations voltage equals Ns by d PSI over d tee.

Transformers, Ns = instantaneous voltage
Transformers, PSI(Ö) = magnetic flux though one turn of the coil
