    Can Corona Discharge Occur Around Charged Glass/Dielectric?

    ...Considering there is NO dielectric breakdown or breaking of glass/dielectric..... Can there be a corona discharge ever around a charged glass/dielectric without a conductor in the vicinity? For instance; take a single-electrode glass high-vacuum tube, charge it to high voltage...

    Attraction force of atoms inside a metal sphere, near a charged plate

    It is a little hard for me to describe what I want to.. (heck, I may not even know exactly what I want to know) :), anyway, If we have a charged solid sphere and I shall put it this way: (Im extremely exaggerating the case here of course) Is the charged sphere trying to pull itself...

    Attraction force of atoms inside a metal sphere, near a charged plate

    mfb, thank yo for the reply which is where I am again not sure if understand this very part correctly or not. 1-You said: " The net force comes from free electrons moving on the surface", I can understand that OLNY the electrons on the sphere-surface facing the plate are the ones responsible...

    Attraction force of atoms inside a metal sphere, near a charged plate

    Hi, I have read about electric charge and tried to understand one particular thing but still couldnt: If we positively charge a big metal plate with very high voltage and approach to it a small solid neutral metal sphere, the smaller sphere obviously will get attracted, i.e. a force will...

    How rapidly can an electromagnet get magnetised and de-magnetised?

    I appreciate your point of view and I am aware of all the above hurdles in my way but as ironic as it is I started to think that the whole idea isn't possible but I am not 100% sure. As I said it actually boils down to the "interaction between the uncoupled electromagnetic field of...

    How rapidly can an electromagnet get magnetised and de-magnetised?

    yungman, all I know is from self taught knowledge, reading everything I ever can. And also before doing/making/building anything I wanted to make sure if it works or not. The final question was the one I posted in my last post before this one.

    How rapidly can an electromagnet get magnetised and de-magnetised?

    Lets see if I get this correctly Maybe the real question is what will the magnet2 do when it encounters the uncoupled field-1 of magnet-1. The electromagnetic-field -1 has almost no mass but has the same magnetic field pole and strength as magnet2. So, will magnet2 get repelled...

    How rapidly can an electromagnet get magnetised and de-magnetised?

    Ok, but doesn't it boil down to the magnetic field strength of the air coil, i.e. how many gauss the small 2nh air coil for instance will output at 500mhz+ with 2amps? this 2nh rf inductor can operate at 3ghz with max current 2.3A and has SRF of 16ghz so we can use it safely at 3ghz and 2A...

    How rapidly can an electromagnet get magnetised and de-magnetised?

    you are correct it is small but shouldn't it e ig since this small force is being applied 500,000,000 times a second if we use 500mhz?

    How rapidly can an electromagnet get magnetised and de-magnetised?

    What makes you think you will get any measurable propulsion out of this? I explained in the post but let me make it clearer. When you separate a magnet from its magnetic field you get a field to react and push against. Thats it really. For instance if we have two such super high pulsed...

    How rapidly can an electromagnet get magnetised and de-magnetised?

    Hi again, I didnt want to start a new thread so here I continue. I decided to let you know what I am working/researching on. If you find that this concept is totally impossible it is fine, but please give it a thought and if it can't work, please specify the the reason why. Anyway the whole...

    How rapidly can an electromagnet get magnetised and de-magnetised?

    Naah, I am trying to reconstruct Teslas Death ray... :wink: Yes, I am aware that I am closing to light, that is sort like the idea. Honestly I have some kind of a little "theory" in my head(for some years now) that I really want to confirm by an experiment. I don't see really why it...

    How rapidly can an electromagnet get magnetised and de-magnetised?

    I wrote dc to not confuse with ac, big difference. Though everything will tend to have a round triangular waveform at such high frequencies, my goal is to have square waves. Anyway I found this: http://apl.aip.org/resource/1/applab/v58/i12/p1253_s1?isAuthorized=no This GaAs...

    How rapidly can an electromagnet get magnetised and de-magnetised?

    Im sorry but I am not quite exactly sure what you mean by "RF" but yes I want to create a rapid DC pulsing in an air- core coil in the 100ghz i.e. an oscillating magnetic field that goes: on off, on off. 10ghz may be enough. But it must be 10ghz minimum Since this is an experiment, none of...

    How rapidly can an electromagnet get magnetised and de-magnetised?

    AlephZero, berkeman Hey and thank you for the info and welcoming. As far as I am concerned there will be no other part in the circuit except the air core electro magnet(well it is going to be hooked to a some kind of signal/function generator), so that's all there is going to be, a coil...
