Calculation of Induced EMF
Given:
- Rate of change of magnetic flux linked with a coil = 1 Wb/min
To find:
- Induced EMF (in volts)
Solution:
The induced EMF (Electromotive Force) in a coil is given by Faraday's law of electromagnetic induction:
EMF = -dΦ/dt
Where,
- EMF = Induced Electromotive Force (in volts)
- Φ = Magnetic Flux (in Weber)
- t = time (in seconds)
Here, the rate of change of magnetic flux is given in Weber per minute. Therefore, we need to convert it into Weber per second by dividing it by 60.
Rate of change of magnetic flux = 1 Wb/min = (1/60) Wb/s
So, the induced EMF in the coil will be:
EMF = -dΦ/dt = -(1/60) V/s
Therefore, the induced EMF in the coil is -1/60 volts or -0.0167 volts. Since the EMF is negative, it means that the direction of the induced current will be opposite to the direction of the change in magnetic flux.
Answer:
- The induced EMF is -1/60 volts or -0.0167 volts.
- Option (C) 1/60 is the correct answer.
