Lecture 1 Notes, 95.657 Electromagnetic Theory I, Fall 2011 Dr. Christopher S. Baird, UMass Lowell 1. Term Overview - [Hand out to each student a printed copy of the “Course Policy”, “Calendar” and read them] - [Hand out to each student a printed copy of the “Lecture 1 Notes”] - All lecture notes are posted on the course website. You are expected to print them out for yourself. - This is a very hard class. I don't curve grades. To pass this class you must: - Read the textbook before the lecture; the chapter sections to be covered are posted online. - Read the class notes before the lecture. - Take notes and ask questions during the lecture. - Reread the textbook after the lecture. - Do all of the homework problems. - The early material may seem a review. You must have this mastered to handle later material. 2.

Steadily moving charges create static magnetic fields. Accelerating charges create changing fields. Relativistic corrections to accelerating charges creating changing fields. Charged particles in quantum states interact with quantized electromagnetic field. Relativistic corrections to charged particles in quantum states interacting with the quantized electromagnetic field.

4. Macroscopic Theory - Quantum theory is required to accurately describe atomic-scale electrodynamics. - Classical electrodynamics is therefore a macroscopic theory. - There is no valid concept of an electron in classical electrodynamics: the word “electron” is hereby banned from this class. Instead we speak of large collections of electrons that behave macroscopically known as “electric charge”. - For mathematical consistency, point charges are defined, but they do not represent electrons. - The point charge
