Field of a circular loop: As shown in the figure, an insulated wire is bent into a circular loop of radius 6.0 cm and has two long straight sections. The loop is in the xy-plane, with the center at the origin. The straight sections are parallel to the z-axis. The wire carries a current of 8.0 A. What is the magnitude of the magnetic field at the origin? (μ0 = 4π × 10-7 T ∙ m/A) 
A) 75 µT
B) 81 µT
C) 88 µT
D) 110 µT
E) 120 µT
