- 4. WORKING PRINCIPLE • Itis based on the principle of production of dynamically induced e.m.f. (electro motive force). Whenever a conductor cuts magnetic flux, dynamically induced e.m.f is prodused in it according to Faraday’s Laws of Electro magnatic Induction. This emf causes a current to flow if the conductor circuit is closed.
