What principle do the Transformers work

Describe in brief on what principle do the Transformers work?




The transformer is a static device which transfers electrical energy from one circuit to the other via inductively coupled conductors-the transformer's coils. Varying current in the first or primary winding makes a varying magnetic flux in the transformer's core and therefore a varying magnetic field via the secondary winding. This varying magnetic-field induces a varying electromotive force (EMF) or ‘voltage’ in the secondary winding. This effect is termed as mutual induction.
