A metallic meter stick moves with a velocity of `2m//sec` in a diretion perpendicular to its length and perpendicular to a uniform magnetic firld of magnitude `0.2T` . The emf induced between the ends of the stick

Text Solution

Verified by Experts

The negative terminal is that end toward which elections are moving due to magnetic force. The magnetic force on electron is acting along `B` , hence `B` is `-ve` terminal of battery.
`e=Bvl=0.2xx2xx1=0.4V`
