A charge particle moves along the line AB, which lies in the same plane of a circular loop of conduting wire as shown in the fig . Then :

Options

A. No current will be induced
B. The current will be clockwise
C. The current will be anti-clockwise
D. The current will change direction as the electron passes through

Answer

D

Explanation

IF electron is moving from left to right, the flux linked with the loop (which is into the page) will first increase and then decrease as the electron passes through it. So the induced current in the loop will be first anti-clockwise and will change direction as the electron passes by.
