NEET (UG) 2024 — Question 13

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:

Option A:
$A B$ and $D C$
Option B:
$B A$ and $C D$
Option C:
$A B$ and $C D$
Option D:
$B A$ and $D C$
Correct

Answer: D

Step-by-step solution

North of magnet is moving away from solenoid 1 so end $B$ of solenoid 1 is South and as south of

magnet is approaching solenoid 2 so end $C$ of solenoid 2 is South.
