  1. Question 1

    Q1. A conductor of length 0.3 m is moving with a velocity of 4 m/s in a direction making an angle of 30 degrees with the magnetic field of 0.8 T. What is the induced EMF?

    • A) 0.36 V
    • B) 0.48 V
    • C) 0.6 V
    • D) 0.8 V

    Answer: 0.48 V

    Explanation: Induced EMF = Blv sinθ = 0.8*0.3*4*sin(30) = 0.48 V. Option A fails due to incorrect angle.
