Questions & Step-by-Step Solutions
If a current-carrying wire is bent into a circular loop, what is the direction of the magnetic field at the center of the loop according to the Biot-Savart Law?
Step 1: Understand that a current-carrying wire creates a magnetic field around it.
Step 2: Recognize that when the wire is bent into a circular loop, the current flows in a circular path.
Step 3: Use the right-hand rule: Point your thumb in the direction of the current flow (around the loop).
Step 4: Curl your fingers around the loop; they will point in the direction of the magnetic field lines.
Step 5: At the center of the loop, your fingers will point out of the plane of the loop.
Step 6: Conclude that the magnetic field at the center of the loop is directed out of the plane of the loop.
