A coil with 400 turns and an area of 0.05 m^2 is placed in a magnetic field that changes from 0.1 T to 0.6 T in 0.1 s. What is the average induced EMF?
Q1. A coil with 400 turns and an area of 0.05 m^2 is placed in a magnetic field that changes from 0.1 T to 0.6 T in 0.1 s. What is the average induced EMF?
Answer: 100 V
Explanation: Average induced EMF = N*A*dB/dt = 400*0.05*(0.6-0.1)/0.1 = 100 V. Option B fails due to miscalculation.
