Induced Voltage Formula

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,

Induced voltage formula

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:

Problem 1: Consider a rectangular coil of 5 turns with a side length of 0.5 m. This coil reaches the magnetic field 0.3T within 10s. Compute the induced voltage?

Answer:

Known values are,
N = 5

l = 0.5 m

B = 0.3T

dt = 10s
