44. As shown in the figure below, a long straight wire carries a current i1 = 30 A and a rectangular loop carries current i2 = 20 A. Take a = 1.0 cm, b = 8.0 cm, and L = 30.0 cm. Which of the following values is closet to the magnitude of the net force generated by i1 in the loop? (μ0 = 4π x 10-7 T•m/A)
(A)3.0x10-3 N
(B)2.0x10-1N
(C)8.0 N
(D)0.3 N
(E)0.05 N
