Physics - EMI/AC Question with Solution | TestHub

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