Vedclass · Answer

(B) According to Lenz's Law,the induced current in the loop will flow in a direction that opposes the change in magnetic flux. As the solenoid approaches the loop,the magnetic flux through the loop increases. The end of the solenoid facing the loop acts as a North $(N)$ pole. To oppose the approach of the North pole,the face of the loop towards the solenoid must also act as a North pole. This requires the current in the loop to be anticlockwise when viewed from the side of the solenoid. However,the observer is on the other side of the loop. From the observer's perspective,looking at the face of the loop that acts as a South $(S)$ pole,the induced current will appear to be clockwise.

$A$ current-carrying solenoid is approaching a conducting loop as shown in the figure. The direction of the induced current as observed by an observer on the other side of the loop will be
