There are two coils in transformer. one is called primary winding and second is called secondary winding. These two winding are inductively linked. The Transformer works on the principle of mutual induction. The principal of mutual induction states that if the current in one coil is changing this changing current will produce changing magnetic flux and this changing magnetic flux will produce EMF in in second coil. The EMF is called statically induced EMF.

Working principle of a transformer: The transformer operates on the principle of mutual induction. When ac supply is applied to primary it circulates ac flux in core which is going to link with secondary. The changing linking flux with secondary produces emf in secondary .

A transformer works on the principle of mutual induction. When an alternating voltage is applied to the primary winding,an alternating current flows through it which generates an alternating flux linking with both the primary and secondary winding. According to Faraday's law of electromagnetic induction, this flux produces an induced emf in the primary and secondary winding. When a load is connected across the secondary winding a current flows through it due to the induced emf.

Principle of Transformer: Transformer works on the principle of electromagnetic induction. When the primary winding is connected to ac supply, applied alternating voltage circulates an alternating current through it. This current flowing through the primary winding produces an alternating magnetic flux. This alternating flux links with secondary winding through the magnetic core & induces an emf in it according to the faraday’s laws of electromagnetic induction (mutual induction).
