Magnetic Field and Ampere's Law

This lecture covers topics related to magnetic fields, Ampère's law, magnetic force, and electromagnetic circuits. It explains the determination of magnetic flux, magnetic field strength, and the circulation of magnetic fields. The instructor discusses the deviation of a compass by an electric current, the generation of uniform magnetic fields, and the helical trajectory of electrons in a magnetic field. Additionally, the lecture explores the magnetic field lines of a rectilinear current and the orientation of magnetic field lines around a wire. Practical experiments and theoretical concepts are combined to provide a comprehensive understanding of magnetic phenomena.
