A bar magnet is passing through a conducting loop of radius R with velocity 
. The radius of the bar magnet is such that it just passes through the loop. The induced e.m.f. in the loop can be represented by the approximate curve:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
When magnet passes through centre region of solenoid, no current / Emf is induced in loop.
While entering flux increases so negative induced emf
While leaving flux decreases so positive induced emf.
