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):

$A$ circular coil is placed near a current-carrying conductor,both lying on the plane of the paper. The current is flowing through the conductor in such a way that the induced current in the loop is clockwise,as shown in the figure. The current in the wire is,

If we move a magnet towards a coil,keeping the $N$ pole in front of the coil,then that side of the coil behaves as which pole?

The magnitude of induced emf is directly proportional to the rate of change of magnetic flux linked with the coil. This statement is known as

What will be the direction of current in the coil $A$ as the switch $S$ is closed?

The magnetic flux through a coil is $4 \times 10^{-4} \ Wb$ at time $t=0$. It reduces to $30 \%$ of its original value in time $t$ seconds. If the e.m.f. induced in the coil is $0.56 \ mV$,then the value of $t$ is: (in $s$)
