The current will change direction as the electron passes by.

Vedclass · Answer

(D) $1$. As the electron moves from $A$ to $B$,it constitutes an electric current in the direction $B$ to $A$ (opposite to the motion of the electron).$2$. According to the Right-Hand Thumb Rule,the magnetic field produced by this current at the position of the loop is directed into the page.$3$. As the electron approaches the loop,the magnetic flux linked with the loop (directed into the page) increases. According to Lenz's Law,the induced current in the loop will be anticlockwise to oppose this increase.$4$. As the electron moves away from the loop,the magnetic flux linked with the loop (directed into the page) decreases. According to Lenz's Law,the induced current in the loop will be clockwise to oppose this decrease.$5$. Therefore,the direction of the induced current changes as the electron passes by the loop.

An electron moves along the line $AB$,which lies in the same plane as a circular loop of conducting wires as shown in the diagram. What will be the direction of current induced,if any,in the loop?
