Transformer

[swapna]

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.

I thought it was a childrens toy.

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
