If it would replaced the cooking chambers walls with fine metal grid,( like in the front ) cause off better observing plasmoids,would be safe , or thats a bad idea?!
@Pujc while such an arrangement would indeed contain the microwave radiation, it would not be safe--particularly if you plan to have plasma discharges occur. If you were to replace the existing faraday cage with another one that is entirely mesh, you must ensure that it is just as insulated and grounded as the one already in the microwave was before it. Otherwise you're likely to electrocute yourself or start a fire. Or both. If you insist on doing this, at least learn the phsics of E&M.
@attheveryend Thank you for the information. I was not going to make such a replacement for the walls, Im electrician worker , but was not learned about plasmoids, and this was just a bare idea.
@Pujc Sure thing. Note that plasma discharges aren't anything special as far as electricity is concerned, but they can conduct a rather large amount of current. If the cage isn't grounded, you'll find youve made a rather large toaster.
The magnets cause the electrons leaving the cathode to go in a circular direction, and not straight at the anode as shown in this video. The motion of the electrons by the vanes of this cavity, cause the resonant chambers to "whistle" with a field at around 2,400,000,000 (usually) cycles per second. It really is as simple as a whistle you blow into, but with several chambers to stabilize the tone, and in the electromagnetic domain. See the Wikipedia article. de AE7EC
@zaphodb777 Don't believe everything Wikipedia tells you because it can be modified by the public. This is from a technical TV program that I'm sure has been well researched by scientists.
@bbzlov I am a licensed extra class amateur radio operator. I have known the theory behind magnetrons for many years. :) Wikipedia is right this time.
@zaphodb777 Although I sincerely wish that the wikipedia article on magnetrons had some freakin math in it. I hate that all I have to go on is the whistling analogy. I have yet to figure out what kind of emission pattern the cathode has, and therefore what actual path the electrons take through the cavity; where the accelerating potential is located and in what direction (or if it's even there at all); what the heck is meant by "electrons bunching together" as coulomb force will not allow it.
@attheveryend The cathode emission is a cloud, accelerated towards the vanes, but in the magnetic field, they bend their path, so spin is imparted. This sets up resonances in the chambers of the tube (minus magnets, it's just a diode), and that causes the whistling to begin. I wish I could post links, but try Googling for "magnetrons explained" (good BBC article) and for simplicity, try searching for WWII magnetrons, and radar equipment (early is simpler). 73 de AE7EC
Excellent Video , finally I get it. I have one question though why is 4000 volts, can the amount of volts be lower than that? And if so what would it be used for?
The one in microwave ovens, no the frequency is a lowend band, chosen for not interfearing for telecommunications and production cost, a ovens magnetron is also not capable of handleing the current required for such a task. But in general yes microwaves currently used as a Non-lethal anti personal (anti-riot) weapon, aswell as Active Denial Systems (ADS) that shoot down missiles

Best magnatron video I've ever seen.
I was under the impression that the microwaves were simply spewing from the tip of a very short wire at the desired frequency.
I didn't even think magnets were involved , thats what I get for spending too much time in radio.
