A coil is placed in a magnetic field that is changing at a rate of 0.5 T/s. If the coil has 300 turns and an area of 0.02 m^2, what is the induced EMF?
Q1. A coil is placed in a magnetic field that is changing at a rate of 0.5 T/s. If the coil has 300 turns and an area of 0.02 m^2, what is the induced EMF?
Answer: 3 V
Explanation: Induced EMF = N*dΦ/dt = N*A*dB/dt = 300*0.02*0.5 = 3 V. Option B fails due to miscalculation.
