A circular coil of radius $\displaystyle 8.0$ cm and $\displaystyle 20$ turns is rotated about its vertical diameter with an angular speed of $\displaystyle 50 \mathrm{rad} \mathrm{s}^{-1}$ in a uniform horizontal magnetic field of $\displaystyle 3.0 \times 10^{-2} \mathrm{~T}$. The maximum emf induced the coil will be \_\_\_\_ $\displaystyle \times 10^{-2}$ volt (rounded off to the nearest integer).
