Two long, parallel wires carry currents of $I_1=3\mathrm{.}05$A and $I_2=5\mathrm{.}20A$ in the directions indicated in the figure below, where $d=23\mathrm{.}5cm.($Take the positive $x$ direction to be to the right.$)$

$($a$)$ Find the magnitude and direction of the magnetic field at a point midway between the wires.

magnitude $T$

direction $-$ counterclockwise from the $+x$ axis

$($b$)$ Find the magnitude and direction of the magnetic field at point $P,$ located $d=23\mathrm{.}5cm$ above the wire carrying the $5\mathrm{.}20-$A current.

magnitude $T$

direction $-$ counterclockwise from the $+x$ axis
