How To Take Apart A Microwave

Step 7 The magnetron

This device, the magnetron, is what heats up our foods...

There is hardly any use for this device, but the magnetron have two very large and powerful ceramic magnets! You can hack the magnetron open and extract the magnets and use them for your other projects.

ummm... you can use the magnetron to build a micro wave gun. basically it can also be used as an EMP device so it does have a use.

[szulli-randall]

Do you think you can show me how? I want to make a Sonic Screwdriver with one of those inside it.

[snateraar]

Mind you, some parts of the casing of the magnetron itself like the pink-ish ring around the outlet may contain berrylium oxide which is not quite healthy.
It's safe as long as you don't inhale it though.

[riff raff]

Yeah, as long as you don't scrap off the beryllium oxide and snort it, you should be okay.

Magnetron Hardly Any Use? I'm not trying be rude but your PDF here showed me how to take apart my microwave so I could get the magnetron. (not for its magnets) Anybody out here that can help wire up my magnetron. I'm really not stupid with electricity, I cant for the life of me get it to do what I'm seeing freaking 14 year olds do. I know its not broken components (have 3 taken apart microwaves.) Is it the ground wire you touch it with? Or is just some other wire not in the circuit. Man I'm so frustrated.

[hbell]

Jesus christ dont power up the magnetron! the electromagnetic radiation could easily kill you, as could the transformer. If you cant wire up the transformer, how would you build an enclosure for the microwaves? Im not trying to offend you, but it sounds far too dangerous.

A bit of additional info on the magnetron  This article gives detail on removing the magnets http://www.repairfaq.org/REPAIR/F_micfaq6.html#MICFAQ_021  Magnetrons contain materials than can be a health hazard if they are reduced to a size where they can enter the lungs, I don't have clue to the actual risk factor, just visit http://en.wikipedia.org/wiki/Magnetron#Health_hazards to decide for yourself.

You could just look at the wiring in the microwave before you start clipping wires.
I highly recommended not to power the magnetron up!

[muttyfutty]

Chill!!!! Firstly why the hell do you want to power up the magnitron? these things are WACKO dangerous! can cause cancer, etc... Maby its best ytou leave that component alone... unless you are firing it up in a propaly shielded and controlled inviroment

[ne171pro]

 Did you know cellphones are microwaves?  

Did you know with phased array antenna, Tesla coil, microwave, oscilloscope and RF generator you can power all your house's with limitless wireless free energy, an so much more?  Even cure aids and cancer.

[muttyfutty]

Totaly Correct,
But there is a huge difference between hand/cell/mobile phones and magnetron (lol)

But, I'm not too certain on all the cure for AIDS thing...
:)

[master key]

You know I don't think a magnetron can cause cancer.

[tristantech]

Actually, exposure to high-power electromagnetic radiation can disrupt cell processes and DNA which may lead to cancer.

[muttyfutty]

Well, According to wikipedia: "Some but not all studies suggest that long-term exposure may have a carcinogenic effect"
As well as produce cataracts.
eek...
not very nice at all!
(do you know how I remove those hyperlinks?)

[knoxarama]

hardly any use? you can make radio transmitters with these strong enough to kill anything that walks in front of it, mostly birds. some scientist guys in the hemelayas stood in front of giant magnetrons to heat themselves up. that can't be healthy...

[LiquidLightning]

And I bet that they all died of cancer or had random mutations by now.

[Aleksa32]

plasmana how to fireup the filament? how many amp's does the transformer need? i tried with a small 6v miniature transformer and it was like a short circuit,i think that something is wrong...

[For Better Or Worse]

In my opinion, it would be sheer stupidity to fire up an unshielded magnetron. Not only would it cause cancer, but if left on for a few seconds, and your body would look like a tv dinner that was just cooked. If you want to fire one up, use sheet metal(steel) as shielding, and be warned that electronics would be fryed and probably your hand to if you stuck it in the why of the microwave beam.

[omnibot]

I don't believe those magnets in the magnetron are neodymium. All I've taken out, although very powerful permanentmagnets, are far from neodymiums.

[Plasmana]

Yeah, neodymium magnets very often have a nickel coating to protect it from corrosion, they look a lot like ceramic magnets, but everybody else says they are neodymium magnets...

[awang8]

They are ceramic magnets. If they're neodynium they'd be powerful enough to crush the magnetron.

[seadonkium]

They are definately Cermamic magnets, Neodymium magnets corriode to a redish brown colour, these magnets don't, also Neodymium magnets this size would Crush your hand, and these magnets are nowhere near strong enough. if you want Nib (NeodymiumIronBoron) magnets you can find them inside Harddisk drives and some Highquality speakers

[dagenius]

Why capitalize "Crush?"

[awang8]

Hmm... I wonder how people found out that magnets crush hands?

[szulli-randall]

That is a funny thought!

[qwertyboy]

actually, the chemical formula for neodymium-irom-boron magnets is NdFeB. just though i'd add my own two cents

[seadonkium]

Because I used to randomly capitalize letters when I typed or wrote
