A coil of 600 turns is threaded by magnetic flux of 8 webers. If this flux is reduced to 5 webers in 3 seconds the induced EMF in the coil will be _____?
Answer: 600V
Explanation
The induced EMF (ε) is given by:
ε = -N(dΦ/dt)
where N is the number of turns, Φ is the magnetic flux, and d/dt is the rate of change of flux.
ε = -600(8-5)/3 = 600V
