How do electric and magnetic fields produce light?

They are two very different models When you think of light as a wave of E and B fields, I advice you to not think of them as photons or particles. But just visualize circular waves in water. This is similar except for the fact that it is in thre... read more

Electric and magnetic fields, no matter if real or just fun math do not produce any particle, not even photons, if we decide to label them as particle. Photons can only be produced by decelerating electrons. To be more exact, one photon is emitted each time an electron jump instantaneously to a lower orbital. read more

A changing magnetic field creates electrical current---an electric field. This concept is used by power generators---large coils of wire are made to turn in a magnetic field (by falling water, wind, or by steam from the heating of water by burning coal or oil or the heat from nuclear reactions). read more

Changing electric fields induce a magnetic field (this is how electromagnets work), and changing magnetic fields induce an electric field (this is how the charger on your electric toothbrush works). The result is that if one oscillates, so will the other, and they will continually induce each other. read more
