A circular loop of radius R carries a current I. What is the magnetic field at the center of the loop according to the Biot-Savart Law?

Step 1: Understand that a circular loop carries a current I.
Step 2: Recall the Biot-Savart Law, which helps us calculate the magnetic field due to a current-carrying conductor.
Step 3: Identify that we want to find the magnetic field at the center of the circular loop.
Step 4: Recognize that the formula for the magnetic field B at the center of a circular loop is derived from the Biot-Savart Law.
Step 5: Use the formula B = (μ₀I)/(2R), where μ₀ is the permeability of free space, I is the current, and R is the radius of the loop.
Step 6: Conclude that the magnetic field at the center of the loop is B = (μ₀I)/(2R).
