Transformer work on the principle of mutual induction when an alternating input is applied in the primary, the resulting current produces a magnetic flux in the secondary coil and an emf is induced in the secondary coil.

Loss of energy:
There is the flux leakage across the coil due to poor designing of core or air gap in the core. It can be minimized by winding one coil over the other.
