Q178 / 180 · KCET 2009 · Physics

Near a circular loop of conducting wire as shown in the figure an electron moves along a straight line. The direction of the induced current if any in the loop is
Figure

  • Correct answer
    A
    variable
  • B
    clockwise
  • C
    anticlockwise
  • D
    zero

Solution

Since, electron is moving from left to right, the flux linked with loop will first increase and then decrease as the electron passes by. Therefore, induced current $I$ in the loop will be first clockwise and then will move in anticlockwise direction as the electron passes by.

Hence, the correct answer is option: 'A'.
