#4. A coil of insulated wire is connected to a battery. If it is taken to galvanometer, its pointer is deflected, because
#5. The self inductance of a coil is a measure of
#6. The coils in resistance boxes are made from doubled insulated wire to nullify the effect of
#7. A magnet is moved towards a coil (i) quickly (ii) slowly, then the induced e.m.f. is
#8. Two identical coaxial circular loops carry a current i each circulating in the same direction. If the loops approach each other, you will observe that the current in
#9. When current in a coil changes from 5 A to 2 A in 0.1 s, average voltage of 50 V is produced. The self-inductance of the coil is
#10. A coil having 500 sq. loops of side 10 cm is placed normal to magnetic flux which increases at a rate of 1 T/s. The induced emf is
#11. In a coil of self-induction 5 H, the rate of change of current is 2 As-1. Then emf induced in the coil is
