Lecture 20: Induced Electric Field, Eddy Currents, Displacement Current
Objectives:- Understand and calculate induced electric fields
- Understand circulating currents called "eddy currents"
- Use displacement currents to explain how a time-varying electric field can induce a magnetic field
- Calculate displacement current in simple problems
- Understand that a current in a coil of wire produces an emf that opposes the original current
