Question
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:
Options
A.$AB$ and $CD$
B.$BA$ and $DC$
C.$AB$ and $DC$
D.$BA$ and $CD$
Solution
Sol. [Key Concept: Electromagnetic induction — Lenz's law (bar magnet & solenoid)]
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.
