Maxwell - Electricity & Magnetism
James Clerk Maxwell: Treatise on Electricity & Magnetism (1873) is the last word on classical E&M
- Ranks with Newton’s work as one of the great accomplishments of physics
Four equations that completely describe all of electricity and magnetism
- 1. Coulomb’s law - relates electric field to charges
- 2. Ampere’s law (Generalized)- moving charge or changing electric field generates a magnetic field
- 3. Faraday’s law: changing magnetic field generates an electric field
- 4. Absence of free magnetic “charges” (only pairs of north-south poles)

- You are NOT responsible for the equations!
