Got super magnets?

[WakonTonka]

If you happen to use a "Sonic Care" electric toothbrush, and change the brush end regularly..... Check out the bottom of the brush -there are two small but powerful rare earth magnets there. I now have about 30 of them stuck to my tool chest and find all kinds of uses for them. I have attached speaker-cloth frames to entertainment cabinets, used a few of them taped on a piece of twine to "fish" wire through my interior walls, used them to hold stuff, etc.

Get a solid grip on each one individually with a good pliers and with a twisting lifting action most of the time the magnet will separate from the base easily. Sometimes you will crack off a piece of the thing. Store 'em on the lid of your tool chest.

My wife thought I was crazy, until I used them to solve a problem of hers.

Thanks. I have thrown several of those away.....never thought to save the magnets.

some microwaves and all non-solid state computer hard drives have uber strong rare earth magnets in them too

 

[sometoyotaguy]

I pull them out of old hard drives. They works great.

i have many, many, many. I remove the magnets from VW coils (coil on plug style). These are about the size of a pencil eraser and VERY strong. My father has made magnetic drain plugs for all his engines, and I've used them as super small, discreet cabinet door "latches".

What vw models have those? Thinking about grabbing some the next time I hit up the junkyard

I bought a "C" battery sized rare-earth magnet at one of the online stores. It lifts 385 lbs and was the largest size they could ship on a plane! It's scary powerful and will hurt you if you get any body parts between it and something magnetic...

I use the other brand one, no magnets there

I stick 3 of them on my Oil Filters at the Bottom. One on the Fuel Hard line right before the Filter and one or two right by the Drain Plug on the Oil Pan.

I leave them on the Oil Filter until they are off the car.

I remove the one on the Fuel Line while the Engine is running right before replacing the Fuel Filter.

I pull the Oil Drain Plug and while the Oil is draining I remove the couple next to the Drain Plug on the Oil Pan. This way everything gets flushed out after it has collected.

I use the ~3/8" X 3/8" Neodymium ones for most applications. They are strong enough to attract if you place one on your palm and one on the back of your hand.


Funny thing is I got the idea when I found a small~1/4" X 1/4" Neodymium Magnet stuck to my Drain Pan one time when changing the Oil. I was like WTF??? Then I was like "GREAT IDEA!" Then I bought a bunch and have them on every rig I own now!


I want the C-Cell size one though!!!! 385 pounds holding capacity is one helluva magnet!

I bet someone is making a run on brush heads on ebay.

Not all of the Sonicare brush heads have the magnets. Checked mine last night and they do not have anything magnetic in them. Yes, these are the Sonicare brand as well.

All 1.8t, 2.0t. VR6, 2.5 engines have these along with most Audi's. Just pop the hood or look at the engine- if they don't have plug wires you should be good to go. There is a little bit of work to get to the magnet, but a BFH makes that quick work, but go easy at first until you find where the magnet is located in that particular coil since some are slightly different.

thanks herb, I take a look next time I get to the 'yard

Never thought to look in an electric toothbrush. Have a few rare earth magnets from PC hard-drives though. But NOT in my workshop. In general magnets are bad in a ferrous metal working environment, especially near your tools. Attracts unwanted particles.

i love all things magnet. i use them for everything, furniture doors, tool holders, etc...

a good site to inform and purchase from. (not associated with at all)

They show up in strange places.
I had a HF tape measure with a bent metal belt clip on it that I didn’t like.
I couldn’t see any screws holding it on though.
When the tape broke I opened the case out of curiosity.
The bent metal clip was held to the plastic case with 6 of those 12 dia x 1/8 thick magnets.
I had to pry them off one by one.
I have them on the end of my tool box.
They work great for holding assembly drawings down in the wind.

Does anyone know how to tell if a certain microwave has these in it?

Take them out of old hard drives.
Got a couple epoxied to a start/stop station, for a motor tester remote pendant.
Takes a fair amount of effort, to remove the thing from any steel or cast iron surface.

I have a couple of these super magnets (whatever they are) I bought at the hardware store. I have them in the lid of my chainsaw box andthey hold onto two 16" chainsaw bars.

Funny thing is a buddy was screwing around with two similar magnets that were much stronger. One of them flipped over the other,went around his thumb and caught the other magnet. Between them was the webbing between his thumb and index finger, resulting in a bleeding ouchie and a few select words.

Iv'e never seen a microwave with neodymium magnets,but they do have large ceramic doughnut magnets

I have used them as a poor man's stud finder. Place one on the end of a string, and swing back and forth along the wall. The magnet will stick to any drywall screws or nail heads under the mud.

 

[Kevin54]

Here is a couple of cool things you can do with the magnets

 

[kbs2244]

metaleltr is right.
The magnets in micro waves are old style donuts.
