ElectroMagnetic InductionHard
Question
The resistanceless wire AB (in figure) is slid on the fixed rails with a constant velocity. If the wire AB is replaced by a resistanceless semicircular wire, the magnitude of the induced current will
Options
A.decrease
B.remain the same
C.increase
D.increase or decrease depending on whether the semicircle bulges towards the resistance or away from it.
Solution
Since 
is same in both cases hence the induced end thus induced current will also be same in both cases.
