DIY How To Disassemble A Magnetron
ฝัง
- เผยแพร่เมื่อ 12 ม.ค. 2014
- I had a defective magnetron (shorted burned connector) so I decided to disassemble it for the two ferrite ring magnets. Caution must be taken to avoid harming the pink insulators on the tube as they could be made of beryllium oxide, which is hazardous if inhaled as dust from a broken insulator.

One of the few you tube videos that are not muffled, garbled or otherwise needing to be replayed 5 times to understand what the teacher is saying. Thank you Bill and may you continue to disciple us DIY fans
@@owlhuman8312 hes not saying that everyone needs to sound like a gigachad but even i have sometimes probles understanding some people even though having max volume.
I'm 63 and throughout my life have torn apart microwaves for the magnets.
Usually with a large screwdriver and hammer.
I remember smashing the insulation every time not knowing at the time it can kill ya.
I searched for your video as i have a microwave oven from the local tip in the ute.
I took the magnetron out last night.
Now i can remove the magnets safely.
Thanks, your directions eady to understand .
Subscribed and looking forwards to more of your work.
So Beryllium exposure must be exaggerated as you are still fine after smashing the insulator.
@@austinscott813 I know these comments are old but there is no Beryllium in household microwaves, it's a kind of alumina.
No harm was done to the insulator in the making of this film
If you carefully cut off the end caps of the core, there's a substantial chunk of solid copper inside.
hacksaw?
Can you imagine I am watched this video exactly after 7 years! Thats an interesting coincidence. Irrespective of that, this has been extremely helpful, I was able to isolate the two ring magnets. They are really powerful. I don't know why did I want to take them out and what will I be doing with them. 😅 As a kid I had a ring magnet from a speaker, I tied a rope to it and will toss it around to search for any nails, iron around, just for the sake of it, some kind of kids game. As an adult I am clueless.
I love how you insist on safety. Nice tutorial.
Just remember avoid the pink insulator just incase he didn't mention it
LOL, yes, almost missed that bit! How annoying to point out that is wasn't "harmed" so many times, then scraping it out of the second magnet with brute force.
He used emphasis. I think everyone would do that if they cared.
what pink insulator?? I don't get?? what's the joke??
@@AWcinema beryllium oxide. Not good stuff to breathe in. Deadly stuff. Look it up. he mentions it at around 1:00...

His voice is quite robotic. Goes perfectly with the subject.
Excellent video and very helpful. Have just disassembled a microwave and am using the microwave casing and bare innards as a housing for an outdoor furnace. Recovered screws, copper wire, transformers, plug, lead, fuse, scrap metal, timer mechanism etc but was aware of the potential dangers of a magnetron disassembly. Having seen this I will now follow the guide and hopefully retrieve the large magnets and copper mesh which I can see. I will however put tape around the exterior ceramic spike as an extra protection beforehand. But many thanks for the advice.
You sound like carl sagan, Steven hawking and neil degrase tyson combined
I think that's the reason why this video is so good
Thanks for a very good disassembly technique of a magnetron
I have a blood blister on the my left hand from the same magnets snapping together strongly! Be careful, they are very strong and got me even though I was trying to be careful. I will leave the magnatron intact from here on out and just focus on the Cu from the transformers, motor and wire. Great, clear video!
Thanks for the information! I'm getting my pliars and screwdrivers ready to go tear one apart.
Thanks! I love magnets, too! Thank you also for stressing the safety issues.
i have experimented with magnatrons for decades and never knew about the berylium insulators. luckily i never broke one. thanks.
+steve whodat They are fortunately very rare but still worth a warning. An argon ion laser tube may also contain this substance.
Glad you emphasized the beryllium issue, many people just don't know.
Bullshit, every magnetron video has the beryllium safety nazi's swarming it.
It's not obvious the ceramic contains a toxic metal on the unit. That is to say there aren't skull and bones or danger labels that jump out and warn you of the danger. I've seen super dramatic danger labels on things far less toxic.
This guy's voice is relaxing.
... that's the way it was.

Can I repair a ded mengnatron? Is it possible boss
thanks for the information on the hazards inside the magnetron.
GREAT VIDEO THE OTHER YOU TUBE GUYS WON"T GO NEAR THE MAGNETRON !! ThanK YOU Again !!!
Unless you go grinding away with a grinder, there is no chance for any dangerous dust. The insulator is very thick and extremely durable. You can throw the rest on the ground and it will not even break, so no need to be afraid of taking it apart.
yeah I have had about 20 lbs of beryllium copper that has been polished into the most brilliant mirrors for over 10 years. It is sealed safe and sound. But i agree that its always best to be safe.
that makes me thing.. I wonder if my beryllium is worth anything.
Good video!, from what I understand a lot of the newer mags use a non-Beryllium based ceramic, but as you demonstrated, its better to be treat them all the same, especially if age is not known.
Most that I get are old, so it is best to proceed with caution. Thanks for watching!
Maybe Mr.Owl knows. Mr.Owl, how many licks does it take to get to the center of a magnetron insulator?
no one has found out, they got berylliosis before they finished
The symptoms of acute pneumonitis following a massive short-term exposure do not become manifest until 3 days. Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home. Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
Thank you so much for the warning! I had no idea.
Awesome. Now I can take my magnetron appart and get the magnets. Thanks.
the connecter that's shorted is actually a capacitor to filter out high frequency interference that would otherwise go to the magnetron. Also, like 99 percent of the time the insulator is aluminum oxide. I've broken quite a few the past few months and I'm fine.
I had to speed it up 2x
Excellent informative video and technique. Thank you for the very important safety tip. Very well explained.
Clear eyes needs to hire this guy for thier commercials if Stiller dyes
Thanks for posting this detailed and very informative video.
Excellent video, thanks Bill!
thanks for the clear video and that unique Inspector Gadget voice explanation!!...
Thank you for the helpful info on taking one apart i have one to take apart but havent done it yet i will still wear my respirator just in case for safety thanks again for the step by step instructions
Very helpful, I can do a video of my own about this now!
Great video sir ty kindly!!!
yes that is the way to do it I will add . disassemble it outdoors with the wind at your back or your side so if you have dust from a broken insulator it will not get inhaled. the magnets are good and unlike speaker magnets there is no glue preventing the removal of them.
Great, Entertaining Video- Thanks for Teaching Us The Safeway! Thanks!
Very nicely explained. Thanks.
Nicely done video very informative thanks!
thank you so much i really appreciated your tutorial it helped me a lot that bras washer is a brass mesh filter...i learned from another video...
Thanks for posting! I actually watched this after I took apart a curbed microwave, which I only picked up for the magnets. So, what did I do? I smashed the magnetron apart with a hammer and a prybar, and broke one of the magnets in the process. I should have watched this first! But on the bright side, now I have 3 magnets...
Excellent and informative video .
Nice video, well done, thank you for sharing the knowledge with us :)
Thanks for sharing, interesting stuff.
Nice and precise!
Great Educational Video-- Thanks!
Sounds like Marvin the Martian
made me snort :D
Don't make the YT poster angry!
My teachers microwave died so he let me and my friend open it up, luckly I saw aussie50's video about the magnetron danger, so I knew not to break that, it's currently on a shelf up high with a do not touch sign in the back room to keep kids away from it. He doesn't let kids in the back without permission so it's fairly safe. Thanks bill great vid!
Very helpful, thank you.
excellent tutorial and close up of the subject, it's a good idea to protect yourself further by taping the beryllium part, (beryllium dust is the dangerous part, it easily bonds with oxygen, and you breathe it - not good) so if you're like me, you have cuts on your hands (wear gloves) from wayward screwdrivers, especially when prying metal.
Oh no. I was moving my microwave around a lot. I have the possible broken glass pieces from the plate didn't get in there and chip anything
@@Handlebrake2 shouldn't be an issue, the plate and turn table are connected to a separate motor, the magnatron has its own sealed compartment, it's designed to create the heat to cook.
Hello Bill, could you please tell me about the high voltage diode that you took out of the magnetron ??? What would be a good use for the item ???? What about electrical values of the item ??? Thanks and have a good day too.
Thanks. It was quite easy after watching your video.
Great video dear sir.
Dear sir.
.read riS
If you were so concerned about damaging the insulators why didn't you wrap them with electrical tape or some other method of encapsulation?
Anyway good video thanks for posting.
I agree 100%! I thought as he was fumbling with the large screwdriver he should have put electrical tape on the
deadly pink insulator. If large screwdriver slipped and hit deadly pink it would hold the breakage within.
Good information sir, Thanks!
Your voice sounds like they put Stephen Hawking and Carl Sagan into a teleporter from the fly and merged the 2 together and you came out the other side
yeah dud he sounds like Stephen Hawking. LOL
microwave effects.
It's over Johnny......it's over!!!!!!
LMAO.. I Know right!
I was thinking Hal 9000 when they finally turned him off.
Thank you Bill
Good GOD man, PARANOIA runs deep in this guy! You would actually not only have to break one of those insulators and crush it to a very fine powder and then breathe it in to your lungs, ON PURPOSE, in order to cause any problems, but you would have to do it with nearly the whole quantity of the insulator for it to be hazardous!
and also the insulators are made of aluminum oxide anyway, it's really in high power microwaves or perhaps really old ones the insulators are made of beryllium oxide. He's still got great content though, and I don't really see much problem with being as safe as possible.
You did have beryllium oxide on that one so good thing you were so careful
Thanks for sharing.
Hell this guy is smashing that thing. Not going to fix that
Everything looks pretty good once it was opened @ 6:40. Still usable if the insulation at the terminals were fixed/replaces?
Like a boss...great video.
How would one go about disposing of the barilium oxyide insulators to negate harm to anyone else or the environment?
Thanks for sharing
Very interesting .Thanks
Great video thank you much
good video i didnt know that there was berilium in an magnatron!
great video
Great video. I just took apart my 1st microwave and broke one of the magnets. Is there anyway to glue the two halves back together? Is there anyway to tell if the insulator is Beryllium or not? can you use the cooler fins for anything? Thanks in advance, Mike
Sped this up to 1.25 and was much better.
i slowed it down to .5 and it sounded like a robot
1.5 is even better
naw that still don't get the weird out
Loved the video. But might I add a suggestion. Wrap the burilum with a couple layers of black tape.
@ 8:26 he says you can use it has a diode. Can someone explain how I would do this as I have no other use for a magnetron. Do I power the heater and use it as one of those old vacuum diodes? Or do I have to modify it? Would it emit microwaves? What purpose does the antenna have or can I use it as the anode as it is connected internally?
Thanks a lot.
Thank you. I will replace a broken magnet by scavenging one.hope I can get same size.
Thanks doctor
wow, i tore apart dozens over the years (my job has quite the collection of ceramic magnets, lol)... when should i expect to start glowing in the dark?
awesome, thank you !!
The Pink One's are the Baryllium Oxide The White ones are Safe 2:13
Thank you.
Does anyone know what the voltage rating of the "diode" would be after disassembling the magnetron?
Hi Bill, This is a very interesting video. I gave it a LIKE
If you used the former magnatron as a diode would it produce x-rays or microwaves or any harmfull emissions without the magnets round it?
Bill Gilmour can the 7:34 aluminum cooling fan(or what ever the name is) can that peice be used for powering a HHO cell, the peice that goes in the water?
Great video. I just took apart a delonghi combi microwave, probably 15 years old. The insulator is a dirty white colour not pink.Is it safe please ?
Thanks mate
Take 1 shot when he says "Diode." Take 2 shots: When he says "Magnet." Take 3 shots: When he says "there's no harm to the insulators."
+Kathryn Davidson ... lol i'm drunk
@KD what do you mean by "Take shots" etc? I dont understand the inference or the slang or what you meant.
She is referring to having an alcoholic drink (like a shot of whiskey).
Hi Bill, I saw your fulgurite video and wondered how you did this? Do you know the minimum electricity required to produce them? We are trying to film the process for a science doc but are alarmed by the use of 12,000 volts. Would be greta to hear from you? Tom
you saved me a lot if i wouldnt watch this video i would die
Kinda like playing with a sleeping rattlesnake that you hope you don't accidentally waken!
I have to say you sound like Inspector Clouseau
Thank you for post ......
you should do more videos on the insulator
Buen video
i like the magnetron internal visualization it helps me understand a lot.i have one thing to ask ,normally most of the time as i observed most of the magnetrons are supplied with a 3 to 4V Ac and up to 10 A current flowing through the filament. what will happen if the supplied voltage to the filament is increased or decreased? what makes the microwave output power high or low ?is is the filament voltage variation or the high voltage side variation ?
Power output is controlled by pulse width modulation of the primary of the power transformer.
What is your disposal method once the magnetron is freed from its mountings?
Thanks 👍
Thanks!
Health hazards[edit] Caution: radiowaves hazard Caution: Poisonous particles for the lungsAt least one hazard in particular is well known and documented. As the lens of the eye has no cooling blood flow, it is particularly prone to overheating when exposed to microwave radiation. This heating can in turn lead to a higher incidence of cataracts in later life.[31] A microwave oven with a warped door or poor microwave sealing can be hazardous.There is also a considerable electrical hazard around magnetrons, as they require a high voltage power supply.Some magnetrons have beryllium oxide (beryllia) ceramic insulators, which are dangerous if crushed and inhaled, or otherwise ingested. Single or chronic exposure can lead to berylliosis, an incurable lung condition. In addition, beryllia is listed as a confirmed human carcinogen by the IARC; therefore, broken ceramic insulators or magnetrons should not be directly handled.All magnetrons contain a small amount of thorium mixed with tungsten in their filament. While this is a radioactive metal, the risk of cancer is low as it never gets airborne in normal usage. Only if the filament is taken out of the magnetron, finely crushed, and inhaled can it pose a health hazard.[32][33][34]
Do you think you get one of them to do x-ray's if you used a liquid recirculating coolant with a lead casing shield?
No where near the voltage level needed for xrays, which require 60-150 kilovolts with on cycle measured in fractions of a second. You can get 'soft xrays' down around 20 kilovolts.
What are those two ceramic bars inside copper coils which goes to magnetron?
great video. would it not be wise to just put a strip of tape around the beryllium on the off chance that you may scratch it?
