Sources of Magnetic Fields and Induction

This lecture covers the generation of magnetic fields, including magnetic dipoles, magnetic fields created by current-carrying wires, and magnetic induction. It explains the non-conservative nature of the Lorentz force and the alignment of magnetic dipoles. The concept of flux, Faraday's law, Lenz's law, and the direction of induced currents are discussed. Applications such as dynamos, wireless chargers, and induction cooktops are also explored. The phenomenon of magnetic levitation with a superconductor is demonstrated. The instructor presents various examples and practical applications to illustrate the principles of electromagnetism and magnetic induction.
