$1.[25$ pts$.]$ A wire bent into a triangle with sides $()/((30/$mathrm$\{$~cm$\},40/$mathrm$\{$~cm$\}/)),$ and $50$ cm forms a closed circuit and carries a current of $1\mathrm{.}0$ A $.$ The wire lies in the $()/(($ x y $/))$ plane, and a uniform magnetic field is directed along the positive $()/(($ y $/))$ axis as in the figure.

$($a$)$ Find the magnitude and direction of the magnetic force acting on the portion of the wire consisting of $()/((30-/))$ and $()/((40(-)/($m$)$athrm$\{$cm$\}/))$ sides.

$($b$)$ Find the magnetic dipole moment vector of the current loop.

$($c$)$ Find the torque $($vector$)$ acting on the current loop.
