Question

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

(a) No current will be induced 

(b) The current will be clockwise 

(c) The current will be anticlockwise 

(d) The current will change direction as the electron passes by

Answer 1

The correct option (d) The current will change direction as the electron passes by

Explanation:

vector e is moving from left to right, the flux linked with the loop will first increase and decrease as electron passes by. So current will be first anticlockwise and change direction as electron passes by.
