A single$-$turn square loop of wire, $2\mathrm{.}00$ cm on each edge, carries a clockwise current of $0\mathrm{.}210$ A$.$ The loop is inside a solenoid, with the plane of the loop perpendicular to the magnetic field of the solenoid. The solenoid has $30\mathrm{.}0$ turns$/$cm and carries a clockwise current of $15\mathrm{.}0$ A$.$

$($a$)$ Find the force on each side of the loop.

magnitude $$Ndirectiondirected away from the center

$($b$)$ Find the magnitude of the torque acting on the loop.
