Motional EMF

A metalic met...

Question

A metalic metre stick moves with a velocity of 2 m $s^{- 1}$ in a direction perpendicular to its length and perpendicular to a uniform magnetic field of magnitude 0.2 T. Find the emf induced between the ends of the stick.

Open in App

Solution

Here l = 1 m, B = 0.2 T,

v = 2 m/s

E = Blv = $0.2 \times 1 \times 2$ = 0.4 V.
