Field of a Circular Loop: as Shown in the Figure

question 88

Multiple Choice

Field of a circular loop: As shown in the figure, a wire is bent into the shape of a tightly closed omega (Ω) , with a circular loop of radius 4.0 cm and two long straight sections. The loop is in the xy-plane, with the center at the origin. The straight sections are parallel to the x-axis. The wire carries a 5.0-A current, as shown. What is the magnitude of the magnetic field at the center of the loop? (μ₀ = 4π × 10^-7 T ∙ m/A)

• A) 25 µT
• B) 40 µT
• C) 54 µT
• D) 80 µT
• E) 104 µT
