Two concentric circular loops of radii \(r_{1}=30 \mathrm{~cm}\) and \(r_{2}=50 \mathrm{~cm}\) are placed in \(\mathrm{X}-\mathrm{Y}\) plane as shown in the figure. A current \(I=7 \mathrm{~A}\) is flowing through them in the direction as shown in figure. The net magnetic moment of this system of two circular loops is approximately :
