  1. Question 1

    Q1. A 1-turn coil has a radius of 0.1 m. The magnetic field around it is 2 × 10^-2 T. What is the magnitude of the induced voltage?

    • A) 5 × 10^-6 V
    • B) 2 × 10^-5 V
    • C) 3 × 10^-3 V
    • D) 1 × 10^-4 V

    Answer: 2 × 10^-5 V

    Explanation: Using Faraday's law of induction. Induced voltage is 2 * pi * r^2 * B * N * (dΦ/dt) = 3.14 * 0.1^2 * 2e-2 * 1 * 1e-4 s^-1.
