The diagram shows magnetic field lines. We move from above to below and back.

Below shows the graph of variation of magnetic flux with time.

Match the following:

When magnetic flux through a coil is changed, the variation of induced current in the coil with time is as shown in graph. If resistance of coil is $10\Omega$, then the total change in flux of coil will be-

Two co-axial solenoids shown in figure. If key of primary suddenly opened then direction of instantaneous induced current in resistance ' $R$ ' which connected in secondary :-

As a result of change in the magnetic flux linked to the closed loop shown in the figure, an e.m.f. . $\mathrm{V}$volt is induced in the loop. The work done (joules) in taking a charge $Q$ coulomb once along the loop is :-

Figure shows three regions of magnetic field each of area $A$ and in each region magnitude of magnetic field decreases at a constant rate $\alpha$. If $\overrightarrow{E}$ is induced electric field, then value of line integral $\oint \overrightarrow{E}·\mathrm{d}\overrightarrow{r}$ along the given loop is equal to,
