Motional EMF: Rod Moving Through Magnetic Field

APPH12-F3EZU5

A thin conducting rod of length $10\text{ cm}$ is oriented north to south, moving through a magnetic field that is directed vertically upward and has a magnitude of $2.0\text{ T}$.

If the rod moves east at a constant speed of $4\text{ m/s}$, what is the emf induced in the rod?

A

$0.0\text{ V}$

B

$0.05\text{ V}$

C

$0.2\text{ V}$

D

$0.8\text{ V}$
