The magnetic flux linked with a circuit of resistance $100\, \Omega$ increases from $10\, \text{Wb}$ to $60\, \text{Wb}$. The amount of induced charge that flows in the circuit is (in coulomb):

In the arrangement shown in the given figure,the current from $A$ to $B$ is increasing in magnitude. The induced current in the loop will

An electric generator is based on . . . . . .

The north pole of a magnet is brought near a metallic ring. The direction of the induced current in the ring will be

Discuss Faraday's experiment of bar magnet and coil for generation of electric current in coil.

$A$ square loop of side $10 \; cm$ and resistance $0.5 \; \Omega$ is placed vertically in the east-west plane. $A$ uniform magnetic field of $0.10 \; T$ is set up across the plane in the north-east direction. The magnetic field is decreased to zero in $0.70 \; s$ at a steady rate. Determine the magnitudes of induced emf and current during this time interval.
