  1. Question 1

    Q1. A coil with 500 turns is placed in a magnetic field that changes from 0.2 T to 0.5 T in 0.1 s. What is the average induced EMF?

    • A) 750 V
    • B) 1500 V
    • C) 3000 V
    • D) 4500 V

    Answer: 1500 V

    Explanation: Average induced EMF = N*dΦ/dt = 500*(0.5-0.2)*A/A / 0.1 = 1500 V. Option A fails due to incorrect calculation.
