Example 1: Magnetic Field due to a Current Loop

  • Derive the magnetic field due to a current loop at the center of the loop

    Uh = CIP

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
