A loop of wire having 50 turns carries a current of `10A` in anticlockwise direction. If diameter of loop is `10cm`, what is the magnitude and direction of magnetic moment of current loop?

Verified by Experts

Here, `N=50, I=10A`,
`r=10/2cm=5xx10^-2m`
`M=? From M=NIA=NI(pir^2)`
`M=50xx10xx3*14(5xx10^-2)^2`
`M=3*925Am^2`
According to right hand thumb rule, direction of `vecM` is perpendicular to the plane of loop and away from observer.
