A horizontal wire `0.8 m` long is falling at a speed of `5 m//s` perpendicular to a uniform magnetic field of `1.1 T`, which is directed from east to west. Calculate the magnitude of the induced ernf. Is the north or south end of the wire positive?

A

`0.15V`

B

`1.5mV`

C

`1.5 V`

D

`15.0V`

Text Solution

Verified by Experts

The correct Answer is:
B
Induced e.m.h.`=B//v=0.3xx10^(-4)xx10xx5`
`=1.5xx10^(-3)V=1.5mV`
