A loop of wire having 50 turns carries a current of `10A` in anticlock

1.	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?
Answer» Here, `N=50, I=10A`, `r=10/2cm=5xx10^-2m` `M=? From M=NIA=NI(pir^2)` `M=50xx10xx314(5xx10^-2)^2` `M=3925Am^2` According to right hand thumb rule, direction of `vecM` is perpendicular to the plane of loop and away from observer.
