A current filament carrying 8A in the z a direction lies along the entire z-axis in free space.
A rectangular loop connecting A (0, 0.2, 0) to B (0, 0.2, 0.3) to C (0, 0.7, 0.3) to D (0, 0.7,
0) to A lies in the x = 0 plane. The loop current is 3 mA and it flows in the z a direction in
the AB segment. Find the force on the loop due to the field of the straight filament.
