An induced current of 2 A flows through a coil. The resistance of the coil is $10 \Omega$. What is the change in magnetic flux associated with the coil in 1 ms ?

A square loop of side length $a$ is moving away from an infinitely long current carrying conductor at a constant speed $v$ as shown. Let $x$ be the instantaneous distance between the long conductor and side $A B$. The mutual inductance $M$ of the square loop-long conductor pair changes with time $t$ according to which of the following graphs?

A square loop of side $$2 \mathrm{~cm}$$ enters a magnetic field with a constant speed of $$2 \mathrm{~cm} \mathrm{~s}^{-1}$$ as shown. The front edge enters the field at $$t=0 \mathrm{~s}$$. Which of the following graph correctly depicts the induced emf in the loop?

(Take clockwise direction positive)

The current in a coil changes from $$2 \mathrm{~A}$$ to $$5 \mathrm{~A}$$ in $$0.3 \mathrm{~s}$$. The magnitude of emf induced in the coil is $$1.0 \mathrm{~V}$$. The value of self-inductance of the coil is
