An arbitrary shaped closed coil is made ...

An arbitrary shaped closed coil is made of a wire of length `L` and a current `I` ampere is flowing in it. If the plane of the coil is perpendicular to magnetic field `vecB`, the force on the coil is

A

Zero

B

`IBL`

C

`2IBL`

D

`(1)/(2)IBL`

Text Solution

Verified by Experts

The correct Answer is:
A

As shown in figure, since `vecL=0`

Hence according to `vecF=i(vecLxxvecB)impliesvecF=0`
