Physics - EMI/AC Question with Solution | TestHub

A straight conducting wire MN of length 4m is rotated in a uniform magnetic field $\overrightarrow{\mathrm{B}}=0.1$ Tesla $(\hat{\mathrm{k}})$ about point O with angular speed $\omega =10\mathrm{rad}/\mathrm{s}$ as shown in the figure. The axis of rotation is parallel to $\overrightarrow{\mathrm{B}}$. Find the potential difference (in volt) between point M and point N.
