Using Biot-Savart Law, what is the magnetic field at the center of a circular loop of radius R carrying current I?

Step 1: Understand the Biot-Savart Law, which states that the magnetic field (B) created by a small segment of current-carrying wire is proportional to the current (I) and inversely proportional to the distance (r) from the wire segment to the point where the field is measured.
Step 2: For a circular loop, every small segment of the loop contributes to the magnetic field at the center of the loop.
Step 3: The distance from any point on the loop to the center is constant and equal to the radius (R) of the loop.
Step 4: The total magnetic field at the center is the sum of the contributions from all the small segments of the loop.
Step 5: Using the Biot-Savart Law, we can derive that the magnetic field at the center of the loop is B = (μ₀I)/(2R) for a single loop.
Step 6: If the loop is complete and we consider the full circular path, we can simplify this to B = (μ₀I)/(2πR).
