AIPMT Mains Physics Electromagnetic Induction Class 12 Questions

In a coil of resistance 10 Ω, 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 condenser of capacity C is charged to a potential difference of V₁. The plates of the condenser are then connected to an ideal inductor of inductance L. The current through the inductor when the potential difference across the condenser reduces to V₂ is

A rectangular, a square, a circular and an elliptical loop, all in the (x - y) plane, are moving out of a uniform magnetic field with a constant velocity, v⃗ = v î. The magnetic field is directed along the negative z axis direction. The induced emf, during the passage of these loops, out of the field region, will not remain constant for:

A circular disc of radius 0.2 meter is placed in a uniform magnetic field of induction $\frac{1}{\pi} \frac{wb}{m^2}$ in such a way that its axis makes an angle of 60° with $\vec{B}$. The magnetic flux linked with the disc is
