Hello, I was just thinking about an inductor and how inductors store energy in a magnetic field around them. I then had a thought about Light speed, lol. If a inductor creates a magnetic field which then starts to move outward at light speed, then is all the energy with that field displaced through out it varying with distance, so the closer to the inductor, the more energy and then less and less the farther out. Now let's say that inductor which is say 1 ft long and 1 ft wide is on for enough time so that the field moving at light speed reaches the moon at obviously Greatly diminished strength.
Now If a magnetic field can not move faster then Light speed (299,792 Km/s ) then what would happen if you set up that inductor which created the field to a circuit where the inductors fall time was on the order of 83 picoseconds or about 1 inch, the distance light would travel in 83 picoseconds. So the question is Would the inductor even be capable of returning the energy in the magnetic field back to the circuit before it turned off since the energy is displaced throughout the field varying with distance.
You know what maybe a simpler question, lol. how is the energy in a magnetic field displaced throughout it? Like is 90% of the energy located within a area of 1 inch around the inductor?
