$A$ conducting square loop of side $L$ and resistance $R$ moves in its plane with a uniform velocity $v$ perpendicular to one of its sides. $A$ magnetic induction $B$ constant in time and space,pointing perpendicular and into the plane of the loop exists everywhere. The current induced in the loop is

The magnetic flux through a circuit of resistance $R$ changes by an amount $\Delta \phi$ in time $\Delta t$. Then the total quantity of electric charge $Q$ which is passing during this time through any point of the circuit is given by:

In Faraday-Henry’s experiment, a coil is connected to a galvanometer. For the deflection of the pointer in the galvanometer, which of the following statement/s is/are $WRONG$? The pointer in the galvanometer deflects -
$(a)$ When the bar magnet is moved towards the stationary coil along its axis
$(b)$ When the bar magnet is moved away from the stationary coil along its axis
$(c)$ When the coil is moved towards the stationary bar magnet along its axis
$(d)$ When the coil and the magnet are moved without relative motion between them

The phenomenon of "Electromagnetic induction" was discovered by which scientist?

In electromagnetic induction,the induced charge in a coil is independent of

$A$ coil of effective area $3 \text{ m}^2$ is placed at right angles to a magnetic field of induction $0.05 \text{ Wb/m}^2$. If the field is decreased to $20\%$ of its original value in $10 \text{ seconds}$, the e.m.f. induced in the coil will be (in $\text{ mV}$)
