A bar magnet moves away from solenoid-1 towards solenoid-2 as shown. What are the directions of induced currents in solenoid-1 and solenoid-2, respectively? [Image]

G1 Physics · Accepted Answer

Step 1: As the magnet moves toward solenoid 2 and away from solenoid 1, the magnetic flux in the two coils changes oppositely. Step 2: By Lenz's law, induced pole faces oppose the approach and oppose the retreat, respectively. Step 3: Use the right-hand grip rule to trace induced current through terminals: the source diagram's correct direction combination is WX and ZY (option D). Final answer: (D) WX and ZY..
