1. A square loop of wire in the x = 0 plane carrying 4 mA in the field of an infinite filament on the z axis, as shown. Determine total force exerted on the loop! 2. Find the force on a straight conductor of length 0.40 m carrying a current of 6.0 A in the -a-direction, where the field is B 3.50 x 10(a + ay) T (0,2,3) (0,5,3) 10 A (0,2,0) (0,5,0)
