Magnetics

The magnetic field existing in a region is given by \(\vec{B}=0.2(1+2 x) \hat{k}\). A square loop of edge \(50 \mathrm{~cm}\) carrying 0.5 A current is placed in \(x\)-\(y\) plane with its edges parallel to the \(x\)-\(y\) axes, as shown in figure. The magnitude of the net magnetic force experienced by the loop is _________ \(\mathrm{mN}\).
