In an ac generator, a rectangular coil of $\displaystyle 100$ turns each having area $\displaystyle 14 \times 10^{-2} \mathrm{~m}^2$ is rotated at $\displaystyle 360 \mathrm{rev} / \mathrm{min}$ about an axis perpendicular to a uniform magnetic field of magnitude $\displaystyle 3.0$ T . The maximum value of the emf produced will be $\displaystyle \_\_\_\_ V$.
$\displaystyle \left(\right.$ Take $\displaystyle \left.\pi=\frac{22}{7}\right)$
