The induced voltage is produced as a product of electromagnetic induction. Electromagnetic induction is the procedure of producing emf (induced voltage) by exposing a conductor into a magnetic field. The induced voltage is described by making use of Faraday’s law of induction. The induced voltage of a closed-circuit is described as the rate of change of magnetic flux through that closed circuit.
Formula of Induced Voltage
The induced voltage formula is articulated as,
Where,
- ε is the induced voltage
- N is the total number of turns of the loop
ΦB = B.A (Magnetic flux)
- B is the magnetic field
- A is the area of the loop
- t is the time
Induced Voltage Solved Example
The solved question of induced voltage is given below:
