Current is flowing in a wire frame kept ...

Current is flowing in a wire frame kept as shown in the figure where EDCF is in y-z plane and AFCB is in x-z plane. Current in the wire frame is i and length of each side is a. Find the magnetic moment

Text Solution

Verified by Experts

Above wire frame can be seen as composed of two rectangular wire frames where current CF of loop EDCF cancels current FC in AFCB
Magnetic moment `vec(M) = vec(M)_(1) + vec(M)_(2)`
`vec(M)_(1)` is magnetic moment of AFCB
`rArr vec(M)_(1) = ia^(2) hat(j)`
`vec(M)_(2)` is magnetic moment of FEDC
`vec(M)_(2) = -ia^(2) hat(i)`
So `vec(M) = -ia^(2) (hat(i) + hat(j))`
