One continuous wire is shaped into a square with sides of length $\backslash ($ L$=4\backslash$mathrm$\{$~m$\}\backslash ).$ One corner of square has been rounded into an arc of radius $\backslash ($ R$=1\backslash$mathrm$\{$~m$\}\backslash ).$ A current $\backslash (\backslash$mathrm$\{$I$\}=10\backslash$mathrm$\{$~A$\}\backslash )$ travels in the counter$-$clockwise direction. Find the magnitude and direction of the magnetic field at point $\backslash ($ P $\backslash ).$
