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