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

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 moemnt `vecM=vecM_(1)+vecM_(2)`
`vecM_(1)` is magnetic moment of AFCB
`impliesvecM_(1)=-a^(2)hatj`
`vecM_(2)` is magnetic moment of FEDC
`vecM_(2)=-ia^(2)hatj`
So `vecM=-ia^(2)(hati+hatj)`
