In a circular loop of radius R carrying a current I, what is the magnetic field at the center of the loop according to the Biot-Savart Law?
Correct Answer: B = (μ₀I)/(2R)
- Step 1: Understand that we have a circular loop with a radius R.
- Step 2: Know that the loop carries an electric current I.
- Step 3: Recall the Biot-Savart Law, which helps us calculate the magnetic field created by a current-carrying wire.
- Step 4: Recognize that at the center of the circular loop, the magnetic field can be calculated using a specific formula.
- Step 5: The formula for the magnetic field B at the center of the loop is B = (μ₀I)/(2R), where μ₀ is the permeability of free space.
- Step 6: Substitute the values of I and R into the formula to find the magnetic field at the center.
