Biot-Savart Law
A "brute force" method of finding the magnetic field due to a length of current-carrying wire
Example 1: Magnetic Field due to a Current Loop
Derive the magnetic field due to a current loop at the center of the loop
Example 2: Magnetic Field due to Long Straight Current-Carrying Wire
Derive the magnetic field strength at a point P located a distance R from an infinitely long current-carrying wire using the Biot-Savart Law
Example 3: Magnetic Field due to A Current Loop
Derive the magnetic field due to a current loop at a point out of the plane of the loop but centered on the loop's axis as shown
