A conductor `ab` of arbitrary shape carries current I flowing from `b` to `a`. The length vector `ab` is oriented from `a` to `b`. The force `F` experienced by this conductor in as uniform magnetic field B is

A

`vecF=-I(vec(ab)xxvecB)`

B

`vecF=I(vecBxxvec(ab))`

C

`vecF=I(vecbaxxvecB)`

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D
`vecF=I(vec1xxvecB)=I(vec(ba)xxvecB)`. We can see that all (A), (B) and (C) options are same.
