Electromagnetic Induction

This lecture introduces the concept of electromagnetic induction, explaining how it couples electrical and magnetic effects by considering a system with moving metal bars immersed in a magnetic field. The instructor demonstrates how the force of Lorentz leads to the separation of charges, creating an induced electric field. The lecture explores the relationship between magnetism and electricity, showing how induced electric fields oppose the separation of charges, leading to equilibrium in the system. Through geometric analysis, the lecture illustrates how the induced voltage varies linearly with time as the bar moves through the magnetic field. Practical applications of creating linear voltage ramps are discussed, emphasizing the fundamental principles of electromagnetic induction.
