★ Must-know
James Clerk Maxwell (1831–1879) showed that a time-varying electric field generates a magnetic field, completing the symmetry with Faraday’s result that a time-varying magnetic field generates an electric field.
Maxwell’s equations, together with the Lorentz force formula, express the basic laws of electromagnetism and predict electromagnetic waves as coupled time-varying electric and magnetic fields propagating through space. — James Clerk Maxwell
The predicted speed of electromagnetic waves was close to , the measured speed of light, leading to the conclusion that light is an electromagnetic wave. — James Clerk Maxwell
