ElectroMagnetic InductionHard
Question
In fig. (a) and fig. (b) two air-cored solenoids P and Q have been shown. They are placed near each other. In fig. (a), when IP, the current in P, changes at the rate of 5 As-1, an emf of 2 mV is induced in Q. The current in P is then switched off, and a current changing at 2 A s-1 is fed through Q as shown in diagram. What emf will be induced in P:-
Options
A.8 × 10-4 V
B.2 × 10-8 V
C.5 × 10-3 V
D.8 × 10-2 V
