A metallic rod of length $L$ is rotated with an angular speed of $\omega$ normal to a uniform magnetic field $B$ about an axis passing through one end of the rod as shown in the figure. The induced emf will be:

A rod rotates about one end in a uniform magnetic field directed into the page, with angular speed omega and rod length L shown.

A
$\frac{1}{4} B^2 L \omega$
B
$\frac{1}{4} B L \omega$
C
$\frac{1}{2} B L^2 \omega$
D
$\frac{1}{2} B^2 L^2 \omega$
