E- and H- fields, acceleration and oscillation of charge! Tying together the basics in only a few minutes takes me to EM propagation, particle accelerators/synchrotrons, bending magnets, power generation, and astronomy. A worthwhile watch over coffee! Enjoyed the trip down memory lane. THANK YOU !

You are welcome.

Hi

[@MichelvanBiezen]

Good morning.

[@zakirhussain-js9ku]

Source of Photon's electric field is oscillating charge. But oscillating charge provided energy & not electric field. Can energy be converted to electric field & vice versa like energy & mass.

[@MichelvanBiezen]

The electric field transports the energy from one location to another through the oscillations that move at the speed of light.

[@vasyllizanets7954]

Thank you. What about magnetic field which is created by spiral (non linear) motion of charged particle? The universe is magnetized. To my mind, direct movement of charged particles is possible in the laboratory only.

[@hythe4936]

So an electric field can exist without a present particle

[@MichelvanBiezen]

There are different ways in which an electric field can be generated. One way is the presence of charges. The other is the chaning magnetic flux through a close loop conductor.

@@MichelvanBiezenYour reasoning is circular. 😉

What color is carbon on the skin in humans? I saw that we are made out of 11 elements

[@MichelvanBiezen]

There is no part of us that is made up of "pure" carbon, but carbon mixed with other elements that form all the molecules, that make up our body. (There are much more than 11 elements in our body)
