okay guys, I had this class the other day (photonics) and we briefly covered Maxwell's Equations in the class. It left me dumbfounded, and I would like to understand these equations a little better. HELP ME, please.

Well you said that you knew the classical equations of Faraday and Gauss' law (etc.). Maxwell's is just the differential form of the classical equations. If you understand the operators to the differential form, then you get it all (if you understand the classical versions). Del Del dot (Divergence) Del cross (Curl) are the only new operators. If you have taken some vector calculus then you know what dot and cross are, they apply to Del like they would any equation. Definition of Del (in rectangular coordinants):  (The lower case delta is partial derivative). Maxwells equations (for refrence): Gauss's electricity integral:  Derivative:  Gauss' magnetism integral:  Derivative:  Faraday integral:  Derivative:  Amperes integral:  Derivative:  If you want the proof of how the integral form magically becomes differntial, I have the proofs in my notes but you might be better off looking online. ( Even I have trouble reading them  ) |
