In the above diagram, a strong bar magnet is moving towards solenoid-2 from solenoid-1. The direction of induced current in solenoid-1 and that in solenoid-2, respectively, are through the directions:

AB and CD
BA and DC
AB and DC
BA and CD
To solve this problem, we will use Lenz's Law and Faraday's Law of electromagnetic induction.Lenz's Law states that the direction of the induced current is such that it opposes the change in magnetic flux.Given: A strong bar magnet is moving towards solenoid-2 from solenoid-1.Let's analyze the situation:1. As the magnet moves towards solenoid-1, the magnetic flux through solenoid-1 increases. According to Lenz's Law, the induced current in solenoid-1 will oppose this increase. This means solenoid-1 will act to repel the approaching north pole of the magnet. Therefore, the induced current in solenoid-1 will flow from A to B.2. As the magnet moves towards solenoid-2, the magnetic flux through solenoid-2 increases. According to Lenz's Law, the induced current in solenoid-2 will oppose this increase. This means solenoid-2 will act to repel the approaching south pole of the magnet. Therefore, the induced current in solenoid-2 will flow from D to C.Thus, the direction of induced current is:• In solenoid-1: AB• In solenoid-2: DCTherefore, the correct option is Option 3: AB and DC.
