a circular coil of 500 turns of wire has an enclosed area of 0.1m square per turn. it is kept perpendicular to a magnetic field of induction 0.2 T and rotated by 180 degree about a diameter perpendicular to the field in 0.1 sec. how much charge will pass when the coil is connected to a galvanometer with a combined resistance of 50 ohms

Area=0.1(500)=50

B=0.2

Flux=B.A=50.(.2)=10

EMF=Flux/time=10/.1=100V

I=V/R=100/50=2A

I=q/t=2 C/sec  i.e 2Columb
