Show Answer
Solution:
Ans. From an observer, the direction of current in the solenoid is anti-clockwise. On displacing it towards the loop, current in the loop will get induced in a direction in order to oppose the approach of solenoid, hence direction of induced current as seen by the observer will be clockwise. 1
