Energy Storage in Inductance

This lecture covers the energy stored in a magnetic field, focusing on an LC circuit and the decay of current in RL circuits. It explains the energy stored in an inductance with a current, the comparison of energy densities in electric fields, and the field enhancement by a ferromagnetic core. The lecture also discusses the Grenoble high field laboratory and how to store energy in a solenoid efficiently. Additionally, it explores the solenoid with a ferromagnetic core, the field density enhancement, and the inductance and energy density calculations. The session concludes with an analysis of LC circuits, specifically the behavior of the circuit when the switch is opened, producing an oscillating voltage signal.
