MHT CET 2025 19th April Morning Shift | Electromagnetic Induction Question 37 | Physics

Two conducting circular loops of radii $R_1$ and $\mathrm{R}_2$ are placed in the same plane with their centres coinciding. If $R_1>R_2$, the mutual inductance M between them will be directly proportional to

$\frac{\mathrm{R}_1}{\mathrm{R}_2}$

$\frac{R_2}{R_1}$

$\frac{\mathrm{R}_1^2}{\mathrm{R}_2}$

$\frac{R_2^2}{R_1}$

A circular coil of resistance ' $R$ ', area ' $A$ ', number of turns ' N ' is rotated about its vertical diameter with angular speed ' $\omega$ ' in a uniform magnetic field of magnitude ' $B$ '. The average power dissipated in a complete cycle is

$\frac{\mathrm{N}^2 \mathrm{~A}^2 \mathrm{~B}^2 \omega^2}{2 \mathrm{R}}$

$\frac{\mathrm{BNA} \omega}{\mathrm{R}}$

$\frac{\mathrm{BNA} \omega}{2 \mathrm{R}}$

$\frac{N^2 A^2 B^2 \omega^2}{R}$
