Assertion $(A):$ The bar magnet falling vertically along the axis of the horizontal coil will have an acceleration less than $g$.
Reason $(R):$ Clockwise current is induced in the coil.

Two identical circular coils $A$ and $B$ are kept on a horizontal tube side by side without touching each other. If the current in the coil $A$ increases with time,in response,the coil $B$

$A$ coil having $n$ turns and resistance $R \, \Omega$ is connected with a galvanometer of resistance $4 \, R \, \Omega$. This combination is moved in time $t$ seconds from a magnetic field $W_1$ weber to $W_2$ weber. The induced current in the circuit is

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 flux linked with a coil at any instant $t$ is given by $\phi = 10t^2 - 50t + 250$. The induced $emf$ at $t = 3 \ s$ is ....... $V$.

$A$ cylindrical bar magnet is kept along the axis of a circular coil. If the magnet is rotated about its axis,then
