A square loop `OABCO` of side of side `l` carries a current `i`. It is placed as shown in figure. Find the magnetic moment of loop.

Text Solution

Verified by Experts

Magnetic of dipole momentum `|vecM|=IA=Il^2`
Direction of magnetic moment is found using right hand rule.
`vecM=(cos30^@(-hatj)+sin30^@(hatj)M`
`=(Il^2)/2(-sqrt3hati+hatj)`
