What is the magnetic field at the center of a circular loop with a diameter of 15.0 cm that carries a current of 1.50 A?

Question

Quizplus · Accepted Answer

The formula for the magnetic field at the center of a circular loop is given by B = (μ0 * I) / (2 * R), where μ0 is the permeability of free space, I is the current, and R is the radius of the loop. The diameter of the loop is given as 15.0 cm, so the radius is half of that, or 7.5 cm. Converting to meters, we get R = 0.075 m. Plugging in the values, B = (4π × 10^-7 T·m/A * 1.50 A) / (2 * 0.075 m) = 1.26 × 10^-5 T. Therefore, the correct answer is C.
