A triangular loop of side `l` carries a current `I`. It is placed in a magnetic field `B` such that the plane of the loop is in the direction of `B`. The torque on the loop is

A

IBI

B

Zero

C

`I^(2)BI`

D

Infinity

Text Solution

Verified by Experts

The correct Answer is:
B
Torque `tau` = NBI A sin `theta`
`theta ` = angle between normal to the plane of the coil and magnetic field .
`theta = 0` In this case .
Torqeue = 0
