Crazy theories taking my freetime

Alright guys, I know this is out there but I am just wondering. Of all the ways to create light, which is a small piece of electromagnetism, why can't one simply induce a strong charged electron field in a magnetic field at the correct...speed, pulse, whatever else it would take, to make light, literally create it from those two things.

Am I missing something? I know they are inversely proportional, on a sine wave x and y traveling in the z. But what stops the ability to do that?

On another unrelated topic, I am theorizing non-friction surfaces. Not like teflon, something usable on say, hypersonic vehicles. The idea is, what if you took a polished surface, as smooth as human error allows, then charge the upper layer of atoms to excite the electron fields enough to fill in the gaps causing friction, to create almost a bubble of just a single electron wall. Sure there would be air pressure shock waves at supersonic, but there would be no friction to heat the surface.

Anyone have ideas, feedback, corrections?

First things first. What is an "electron field"?

Light CAN be created directly from current flowing in a wire. It's generally in the kHz-MHz range though. Think antenna and radio.

Try this one: Free-electron laser - Wikipedia, the free encyclopedia

They already have trains that use a magnetic field so that it basically hovers 10mm above the track, it is called a Maglev and it travels at speeds of 300mph

Cypragon, yes what I was thinking was visible light. Its easy to do with radio and micro waves, but what meatball posted is like what I was thinking about. That's insane...Haha exactly what I was thinking about.

Yes giorge I am familiar with magnetic fields, but that wouldn't work for friction. As far as air touching the rest of the body.

I think an entirely frictionless surface could be used also as a physical deterrent. Projectiles such as armor piercing rounds, or micro asteroids traveling in deep space would more than likely not harm the surface.

Think light bulb... 60Hz... Can even be done with DC...

Light bulbs produce light with heat, not by a magnetic field.

Is this not the way a cathode ray tube works? Propelling electrons at the back side of the screen to produce light? Although you need it to be in a vacuum to get the electrons to get enough speed to produce light when they collide with the screen.

I think it is the electrons hitting Phosphors that creates the light.
It is the Phosphors not the electrons directly that emit light.

yes, i think that is how the tv's worked.

anyone think a diy free electron laser is possible?

Light bulbs work my incandescence. Basically the filament gets so hot that the energy emitted starts to rise into the visible spectrum. However this isn't too efficient, as a greater portion is emitted as IR and some UV as well. Which is why standard light bulbs get really hot.

With fluorescent light bulbs, the inside of the tube is filled with a mercury gas mix, which when it's ionized generates UV light. This is how germicidal tubes work.

But, when we want visible light, we coat the inside of the tube with phosphors, which change the UV light into visible light.

Cathode ray tube TV's work with an electron gun; basically, electrons are fired at 3 different phosphors on the front of the screen... If you get close enough to the TV you can actually see the 3 colors, red blue and green.

It "shoots" out electrons or, refreshes the screen 60 times a second, or a 60 hertz refresh rate.

To get electrons to emit light in the visible spectrum via electricity without using any phosphors or incandescent methods, you'd have to somehow make an oscillator that works in the terahertz range, which, is basically impossible with today's semiconductor switches and whatnot.

Though, I guess you could technically argue that LED's, and laser diodes are oscillators, since they emit visible light without incandescence, or phosphors.

"induce a strong charged electron field in a magnetic field at the correct...speed, pulse, whatever else it would take, to make light"

Isn't that a plasma ?

"then charge the upper layer of atoms to excite the electron fields enough to fill in the gaps causing friction, to create almost a bubble of just a single electron wall"

But the electrical bonds wouldn't be strong enough in a single layer of atoms to resist anything with even the slightest mass. A slight breeze would overwhelm the forces you make.

Just my thoughts on it.
:thinking:

A magnetron is what you seek. It produces light (in the microwave region) by swirling electrons around in a vacuum inside a magnetic field using cavity resonance to create an EM wave. You would simply need much smaller resonant cavities. The problem is that the cavity/magnet housing would not be transparent to anything above radio wave (incl. microwave) EM bands, so that is why it is not done.

Invent transparent aluminium then you can have what you want.

Strictly speaking, mercury already produces visible light. The phosphors serve to improve the color rendition and luminous efficacy. Here's a tube half-with, half-without phosphors.

Not even the counter charge wouldn't keep the field up?
I think plasma is superheated gas. I can do that with a grape, cup, and microwave... haha

Clear aluminum....that I think actually has been made...

Was that Star Trek 2 or 3?
