Can electromagnetic energy be stored

electromagnetic radiation

Why is it, then, that an inductor such as simple copper wire loop, can "store" energy in it as an electromagnetic field? Wouldn''t the photons or waves of EMF just fly away into space and be lost (the energy would be lost, not stored), how is it that this energy is stored as if the photons would fall back down and hit the wire to create current

electromagnetism

Energy can be stored in a gravitational field. Think black hole mergers, mass is converted directly into gravitational field energy with changes in that field in the form of waves. The waves can do work on the rest of the universe by wiggling everything very slightly.

electromagnetism

If standard Poynting expressions for EM energy are adopted, then vanishing fields $mathbf E,mathbf B$ in vacuum indeed imply zero EM energy density there. So in this context, PhysicsDave is wrong. Although PhysicsDave did not explain what he means, his statement could be true if non-standard expressions for EM energy density and EM energy

Energy

Potential energy is not "stored energy". Energy can be stored in motion just as well as it can be stored in position. Is kinetic energy "used up energy"? kinetic energy. electromagnetic radiation — disturbance of electric and magnetic fields (classical physics) or the motion of photons (quantum physics)

What happens to the energy when waves perfectly cancel each

$begingroup$ The energy is always stored in the medium as potential energy. Air and water are elastic, the EM field stores energy but we cannot observe it directly. but rather to the accepted definitions of the electromagnetic energy and momentum. Perhaps we may need to modify these definitions in order to preserve the energy–momentum
