In this given figure if magnetic field increases with time then pattern of induced electric field lines will be :-

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

A metallic ring is dropped down, keeping its plane perpendicular to a constant and horizontal magnetic field. The ring enters the region of magnetic field at $t=0$ and completely emerges out at $t=T \sec$. The current in the ring varies as

A long solenoid has $500$ turns. When a current of $2 \mathrm{A}$ is passed through it, the resulting magnetic flux linked with each turn of the solenoid is $4\times {10}^{-3}$ Wb. The self-inductance of the solenoid is

The current (I) in the inductor is varying with time according to the plot shown in figure.

Which one of the following is the correct variation of voltage with time in the coil ?

In a coil of resistance $10 \mathrm{\Omega }$, the induced current developed by changing magnetic flux through it, is shown in figure as a function of time. The magnitude of change in flux through the coil in Weber is

A conducting square frame of side $a$ and a long straight wire carrying current $I$ are located in the same plane as shown in the figure. The frame moves to the right with a constant velocity $V$. The emf induced in the frame will be proportional to:
 

An electron moves on a straight-line path $XY$ as shown. The $abcd$ is a coil adjacent to the path of the electron. What will be the direction of the current, if any, induced in the coil?
