Ampère-Laplace Law: Magnetic Field Calculation and Applications

This lecture covers the derivation and application of the Ampère-Laplace law (or Biot-Savart law) for calculating the magnitude and direction of magnetic fields generated by currents. It explains how to apply the law to different wire configurations, perform integrations, and evaluate magnetic fields around straight wires and current loops. The integral forms of the law for wire sections and surface currents are discussed, along with practical examples like determining the magnetic field of a rectilinear wire and a current loop. The lecture concludes with considerations on calculating magnetic field strength along the central axis of a loop.
