The diagram above illustrates a bar magnet near a coil connected to a galvanometer, When the magnet is rapidly moves towards the coil i. e.m.f. is induced in the coil ii. the galvanometer needle deflects iii. the magnet is attracted by the coil. Which of the statements above is/are correct?
Attached Figure / Diagram
A
i only
B
ii only
C
iii only
D
i and iii only
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Moving the magnet changes flux, inducing emf (i) and current that deflects the galvanometer (ii). By Lenz’s law the induced current repels the approaching magnet, so (iii) is false.
