Given figure shows a coil bent with all edges of length `1 m` and carrying a current of `1 A`. There exists in space a uniform magnetic field of `2 T` in positive y-direction. Find the torque on the loop.

Text Solution

Verified by Experts

The correct Answer is:
`2hatk`
The torque of system = Torque on toop `[AFGH+BCPE+ABEF]`
`ISB(-hati)+ISB(hati)+ISB(hatk) (I="current",S="area of loop",B="magnetic field")`
`=ISB hatk`
`=1xx1xx2 hatk=2hatk units`
