Electric fields and magnetic fields interact to produce electromagnetic waves from "summary" of The World of Physics 2nd Edition by John Avison
The interaction between electric fields and magnetic fields is a fundamental concept in physics that gives rise to electromagnetic waves. When an electric field changes with time, it generates a magnetic field. Similarly, when a magnetic field changes with time, it produces an electric field. This interplay between electric and magnetic fields forms the basis of electromagnetic wave generation. Electromagnetic waves are self-sustaining oscillations of electric and magnetic fields that can travel through space. These waves propagate at the speed of light, which is approximately 300,000 kilometers per second in a vacuum. The relationship between electric and magnetic fields in electromagnetic waves is described by Maxwell's equations, which form the foundation of classical ele...
