A coil with 600 turns is placed in a magnetic field that changes from 0.3 T to 0.8 T in 0.15 s. What is the average induced EMF if the coil's area is 0.04 m^2?
Q1. A coil with 600 turns is placed in a magnetic field that changes from 0.3 T to 0.8 T in 0.15 s. What is the average induced EMF if the coil's area is 0.04 m^2?
Answer: 80 V
Explanation: Average induced EMF = N*A*dB/dt = 600*0.04*(0.8-0.3)/0.15 = 80 V. Option B fails due to miscalculation.
