What are Maxwell's equations and how do they describe the interrelation of electric and magnetic fields?
Maxwell's equations are four equations that describe the production and interrelation of electric and magnetic fields. They express experimental laws and are based on James Clerk Maxwell's description of electromagnetic fields. The four statements of these equations describe the divergence of electric field from electric charge, the absence of isolated magnetic poles, the production of electric fields by changing magnetic fields, and the production of circulating magnetic fields by changing electric fields and by electric currents.
What is the difference between Coulomb's law and Faraday's law of induction in the context of Maxwell's equations?
Coulomb's law describes the Coulomb force between electric charges, while Faraday's law of induction describes the production of electric fields by changing magnetic fields. Both laws are expressed in Maxwell's equations as the first and third statements, respectively.
What is the most compact way of writing Maxwell's equations, and what are the symbols used in this notation?
The most compact way of writing Maxwell's equations is in differential form, using the vector analysis operators div (divergence) and curl. The symbols used in this notation include rho (charge density), J (current density), E (electric field), B (magnetic field), D (field quantity proportional to E), and H (field quantity proportional to B). The four Maxwell equations in this notation are: (1) div D = rho, (2) div B = 0, (3) curl E = -dB/dt, and (4) curl H = dD/dt + J.
