The magnitude of the earth's magnetic field at a place is `B_(0)` and angle of dip is `delta.` A horizontal conductor of lenth/lying along the magnetic north-south moves eastwards with a velocity v. The emf induced acroos the coductor is

A

Zero

B

`B_(0)lvsindelta`

C

`B_(0)lv`

D

`B_(0)lvcosdelta`

Text Solution

Verified by Experts

The correct Answer is:
B
It will cut vertical component `B_(V)`
`e=B_(V)lv=B_(0)lvsindelta`.
