MDCAT Physics MCQ #785

  1. Question 1

    Q1. A conductor is moving with a velocity of 5 m/s in a direction making an angle of 45 degrees with the magnetic field of 0.9 T. If the length of the conductor is 0.4 m, what is the induced EMF?

    • A) 1.27 V
    • B) 1.5 V
    • C) 1.8 V
    • D) 2.0 V

    Answer: 1.27 V

    Explanation: Induced EMF = Blv sinθ = 0.9*0.4*5*sin(45) = 1.27 V. Option B fails due to incorrect angle.
