$3)$ Fig. $28-6$ shows two long, parallel current$-$carrying wires. The wires carry equal currents $\backslash (\backslash$mathrm$\{$I$\}\_\{1\}=\backslash$mathrm$\{$I$\}\_\{2\}=20\backslash$mathrm$\{$~A$\}\backslash )$ in the directions indicated and are located a distance $\backslash (\backslash$mathrm$\{$d$\}=0\mathrm{.}5\backslash$mathrm$\{$~m$\}\backslash )$ apart.

Calculate the magnetic field $($magnitude and direction$)$ at the empty corner from $\backslash ($ I$\_\{1\}\backslash ).(3$ points$)$

Calculate the magnetic field $($magnitude and direction$)$ at the empty corner from $\backslash ($ I$\_\{2\}\backslash ).(3$ points$)$

Calculate the total magnetic field $($magnitude and direction$)$ at the empty corner. $(3$ points$)$
