A triangular loop of side 1 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

lBl

B

zero

C

`l^(2)Bl`

D

infinity

Text Solution

Verified by Experts

The correct Answer is:
B
Torque `tau=NBi Asintheta`
`theta` anlge between normal to the plane of the coil and magnetic field.
`theta=0` in this case.
Torque =0
