Flashcards in Electromagnetism Deck (3)
State Faraday’s law of electromagnetic induction
The induced e.m.f is directly proportional to the rate of change of magnetic flux linkage
A magnet is moving into the centre of a flat circular coil of wire. A current is induced in the coil. Use ideas about energy conservation to state and explain the polarity of the face of the coil nearer the magnet
North Pole, there is a repulsive force between the magnet and coil and the work done against this repulsive force is transferred to electrical energy in the coil.
