A conducting circular loop of radius r carries a constant current i. It is placed in a uniform magnetic field`vecB` such that vecB is perpendicular to the plane of the loop. What is the torque acting on the loop?

A

`zero`

B

`irvecB`

C

`3pirivecB`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
If a coil (loop) is placed in a transverse uniform magnetic field, then the torque acting on the coil is always zero.
