State Faraday's laws of electromagnetic induction.
State Faraday's laws of electromagnetic induction.
Faraday's First Law:
Whenever a conductor is placed in a varying magnetic field an EMF gets induced across the conductor (called as induced emf), and if the conductor is a closed circuit then induced current flows through it.
Magnetic field can be varied by various methods -
1. By moving magnet
2. By moving the coil
3. By rotating the coil relative to magnetic field
Faraday's Second Law:
Faraday's second law of electromagnetic induction states that, the magnitude of induced emf is equal to the rate of change of flux linkages with the coil. The flux linkages is the product of number of turns and the flux associated with the coil.
According to Faraday's law of electromagnetic induction, rate of change of flux linkages is equal to the induced emf:
So, E = N (dΦ/dt) (volts)
