An electron moves on a straight line path `Y Y'` as shown in figure. A coil is kept on the right such that `Y Y'` is the plane of the coil. At the instant when the electron gets closest to the coil (neglect self-induction of the coil)

Options

A. the current in the coil flows clockwise
B. the current in the coil flows anticlockwise
C. the current in the coil is zero
D. the current in the coil does not change direction as the electron crosses point `O`

Explanation

Magnetic field is out of the plane and as the electron moves, the field decreases. From Lenz's rule, the current in the coil is anticlockwise.
