A wire carrying a current `i` is placed in a uniform magnetic field in the form of the curve `y=asin((pix)/L)0 lexle2L`. The force acting on the wire is

`(iBL)/(pi)`

iBL`pi`

`2iBL`

zero

Text Solution

Verified by Experts

The correct Answer is:

Shortest distance between end points of wire is
2L so force
` F = I ( 2L) b sin 90 ^(@)`
