# Ram pedals a stationary bicycle whose pedals are attached to a 1000 turn coil of area 0.10 $m^2$. The coil rotates at half a revolution per second and it is placed in a uniform magnetic field of 0.01 T perpendicular to the axis of rotation of the coil. What is the maximum voltage generated in the coil?

$\begin{array}{1 1} 0.314V \\ 3.14 V \\ 1.57 V \\ 0.157 V \end{array}$

Here $f = 0.5 Hz$; $N =1000$, $A = 0.1 m^2$ and $B = 0.01 T.$
$\varepsilon_0 = NBA (2 \pi v) = 1000 \times 0.01 \times 0.1 \times 2 \times 3.14 \times 0.5 = 3.14V$
