Magnetostatics: Electric Current and Magnetic Fields
This lecture covers physical models for micro and nanosystems, the interaction between electric current and magnetic fields, Ampère's law, magnetic fields due to straight wires, solenoids, and different materials, as well as electromagnetic induction and Faraday's law. It also explains the Biot-Savart Law, magnetic field calculations, and the relationship between changing magnetic flux and induced emf. The instructor discusses the behavior of magnetic fields in various materials, including ferromagnetic, paramagnetic, and diamagnetic substances, and provides examples and exercises to reinforce the concepts.
