A square current loop lies flat in the x-y plane with its sidesparallel to the x and y axes. The side of the square is a. Thecurrent flowing in the loop is I, in the CCW direction as viewedfrom above. A uniform magnetic field ~B = B0(^i/sqrt(2) + ^k/sqrt(2)) is applied to the loop.
(a) Find the magnetic force (magnitude and direction) on each sideof the
loop. Check that the sum of the four forces equals zero.
(b) Find the torque (magnitude and direction) on the current loop.
