Laws of magnetic induction, Electrical Engineering

Assignment Help:

The observations from these experiments led to 'The Laws of Electromagnetic Induction'

1)  'If the magnetic flux threading through an electrical circuit changes, then an e.m.f. is induced in the circuit'.

2) 'The magnitude of the induced e.m.f. is proportional to the rate of change of the magnetic flux threading the circuit'. (Faraday's Law) 

3) 'The induced e.m.f. has a direction such that the current which flows (or would flow if the circuit is completed) gives rise to a magnetic field that opposes the change in the magnetic field producing it'.    (Lenz's Law)
