26.6 Maxwell’s equations and electromagnetic waves

Maxwell’s equations describe the behaviour of electric fields and magnetic fields; a more detailed introduction appears in post 25.12. Equations (1)-(4) (highlighted above) are Maxwell’s equations in vector notation. Here E is an electric field, B is a magnetic field, ∇ is the vector operator del, q is charge, ε0 is the permittivity of free… Continue reading 26.6 Maxwell’s equations and…
