Q. 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 isPhysics Question Image

KCETKCET 2009Electromagnetic Induction

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.
