In given figure, P & Q lie on xz plane and S & T lie on yz plane. The direction of magnetic moment of the loop carrying current I is given by :-

A

`(hati+hatj)/(sqrt(2))`

B

`-((hati+hatj)/(sqrt(2)))`

C

`(hati+hatk)/(sqrt(2))`

D

`(hati-hatk)/(sqrt(2))`

Text Solution

Verified by Experts

The correct Answer is:
B
For PQRU
`vec(mu)=-Ia^(2)hatj`
For RUTS
`vec(mu)=-Ia^(2)hati`
`mu_("net")-((hati+hatj)/(sqrt(2)))`
