Relay Back Emf - EMF Relay | Running Races UK | Edinburgh Marathon Festival : Calculation of the average back emf requires specific details about the circuit.. A back e.m.f.(also called a counter e.m.f.) is an emf created across an inductor by the changing magnetic flux around the conductor, produced by. The back emf describes the coefficient between the generated voltage and the speed of the motor v/m/s. The back emf in the relay coil attempts to keep current moving after it has been switched off. Join our community of 625,000+ engineers. Now whenever the solenoid is turned off, back emf is generated, resulting in resetting the arduino, which powers and controls the relay circuit board.
