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.
