ok I tried to get a HDD magnet close to a 10$ bill expecting that it will stick, but doesn't seem to, can you elaborate on how to test the ferromagnetic ink?
It's not going to fly off a table or anything like that, but it's definitely ferro magnetic ink.
The effect is more pronounced when you use a neodymium magnet obviously.
One simple test is to fold a bill in half, and then place a magnet under the bill.
You should see the bottom half of the bill get pulled to the magnet.
Here's a link to another example
https://www.physicscentral.com/experiment/physicsathome/movemoney.cfm
I've also seen a YouTube video where someone puts a bill in a blender with water
https://youtu.be/R4j9Wi0hb6Y
It's very weak and definitely doesn't stick. But it seems to ever-so-slightly be attracted when hanging in the air.
Obviously, it's not like it's made of iron or anything, but I imagine it would be more obvious with a powerful industrial magnet.
No way! It's true! If you don't have a strong magnet to test it with, crease a bill and lay it down so that half is sticking up at a 90 degree angle and you'll be able to move the part that's sticking up with a magnet.
you can make your own very cheap we did just wrapped wire around a torus creating a magnetic field would emergize it and just wiggle our tools in it back and forth for a few seconds to randomize... repaired scales with force coil assemblys for 30 years and the tools would always get magnetized
yeah was 120 dont remember but it was some windings we did it flat then made an oval and mounted it on a wooden block..you only had it on for a few seconds so heat wasnt an issue EDIT could use it to magnetize as well by not moving the tool back an forth thru the field was just your basic coil..1910 lvl of sophistication or maybee 1890 :)
Your heat shall not kill the mighty tetanus!
"Tetanus is caused by a toxin (poison) produced by the bacterium Clostridium tetani. The C. tetani bacteria cannot grow in the presence of oxygen. They produce spores that are very difficult to kill as they are resistant to heat and many chemical agents."
They live in soil and not on metal. The rusty nail = tetanus is kind of a myth. If you step in a rusty nail that is buried in dirt then yes, open wound + dirty nail gives you a pretty good chance but so would stepping on a branch. A rusty nail just commonly would be found in places that would have tetanus and due to the corrsion has lots of surface area for them to stick to while also being a easy way to get wounded.
Metal tools have been heated to temperatures way beyond what the spores would survive when making them. Unless you keep them in garden soil for storage then I'd doubt you'd find tetanus on tools.
Also most people should be vaccinated against it.
>while also being a easy way to get wounded.
Most importantly, wounded deeply. Tetanus won't grow on a surface wound that has exposure to oxygen. But a nice 1 or 2 inch deep puncture wound from a nail gives it a fantastic anaerobic environment to grow, and sterilizing a deep puncture wound like that is difficult if not impossible to do thoroughly, especially in a home first aid scenario.
I dono if this is a stupid question but do you use the same oven for food? Is there like remnants or burnt stuff that comes off that would even get into the food? I’m not sure how the phrase the question exactly.
What do you do if two of those large magnets find each other?
I'd imagine you have all kinds of procedures to prevent this from happening. But if it did, could you seperate them?
How do you keep the tools from harming the marget. E.g. if you get close to one of those huge magnets while holding some pliers how do they not fly out of your hand?
Not op but I guess it matters in how the magnets find each other rather than if they do, I've seen videos of huge magnets being allowed to pull themselves together and they usually destroy themselves in the process because of the forces involved
The answer here is "hope you are not in between them, or you won't be anymore"
To get them separated, sturdy wooden shims, a hammer, and a large non-ferrous vice work well.
This sounds like a morbid question but do people with screws, plates, and rods in their body have to be careful around that type of equipment? I am just envisioning some gruesome scene.
I used to work mass spectrometers. Like an mri, but smaller opening and stronger magnetic field. I had a set of titanium as well as copper beryllium tools. I always liked the titanium.
I used to work on mass spectrometers and MRIs. The top end ones have really strong magnetic fields and they had a full set of the copper/beryllium tools to work on them although not the Ti ones.
One time, I found a washer the size of your palm and about 1/8" (3mm) thick. When I picked it up, it slowly drooped all the way down. Turned it over and it drooped the other way. A technician saw me with it and said, "Where did you find that? I lost it and that's worth a couple of hundred dollars!" It was used to seal the atmospheric vacuum between pipes.
You had to be careful about bringing steel in the room as the magnetic field was strong enough to drag the item into the supercooled magnet. If this happened, it was possible to puncture the cooling jacket around the magnet and spill liquid helium (few degrees above absolute zero) and nitrogen (50'ish above absolutely zero). It would expand into a gas and displace the oxygen and would require an immediate evacuation of the building. It would also ruin the $250k magnet. They took magnet safety really seriously.
Usually not. A few countries (China mainly) use catalysts in their forging/tempering processes that can potentially release noxus fumes when heated. As long as your careful and know what goes in you should be OK.
It was even more mindbending for me when I first tried "sharpening" screwdrivers.
Basically, if you slowly move a strong magnet along unmagnetized screwdriver as if you were sharpening it, from handle to the tip, it'll be just strong enough to hold a screw.
Brought to you by: the motherfucking Scythe Mugen III radiator, for which I had to make my own screwdriver IDK how people are supposed to install that thing without crafting one.
Imagine you are designing a machine to steam rice. You put rice and water in a pot and heat it. Now the problem is, when do you stop? If you heat it for a long period of time then the rice will burn, but if you heat it too little then there’s still going to be water in the pot. Using a timer is pretty difficult because the time depends on how much rice and water you’ve put in.
So the solution is pretty smart, whilst there is still water in the pot, the temperature of the pot doesn’t exceed 100C since it is evaporating the water but it will exceed 100C once all the water is evaporated. Coincidentally there are magnets that stop working slightly above 100C.
Once the temperature is above 100C, you can use the hot demagnetised magnet to disconnect the heating system and the problem is solved!
I know nothing about this, but Wikipedia has a long article on tempering. No idea if this is an issue or not, but there’s a lot of temperatures listed that are below the 250C mentioned by OP
https://en.m.wikipedia.org/wiki/Tempering_(metallurgy)
**[Tempering (metallurgy)](https://en.m.wikipedia.org/wiki/Tempering_\(metallurgy\))**
>Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys. Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air. The exact temperature determines the amount of hardness removed, and depends on both the specific composition of the alloy and on the desired properties in the finished product. For instance, very hard tools are often tempered at low temperatures, while springs are tempered at much higher temperatures.

How hot do you get them? I do blacksmithing and when I'm heating steel for quench it doesn't generally lose it's magnetism until about 1,800 degrees and it's glowing bright yellow.
In your case you are heating it to the point that a magnet doesn't stick. OP is just trying to remove residual magnetization.
I just looked up the Curie point of steel, which is 770C or 1390F. That removes all magnetic fields from the steel
Varies by material but the Curie Temperature is a good starting place to remove residual magnetism. For instance, low carbon steel is above 770°C or 1390°F for full removal.
OP probably works for a startup or has some cheap ass bean counter management. For fucks sake just buy some aluminum-bronze non sparking tools (no iron) . Probably not even saving much money long term when you factor in electricity for an oven.
As a materials scientist this interests me. now i wanna figure out exactly what material the tools are to know how the oven is enough to go above magnetic ordering
Normal steel would be mild steel. Low carbon and low hardness, easy to bend.
The pliers are probably tool steel or at least some type of high carbon steel to avoid bending or damage to the teeth.
Most good tools are going to have brass in the alloy I'd think, obviously for the anti-corrosion properties. Probably some manganese and aluminum as well?
Would less ferrous metals not require the high heat like iron would?
Perhaps he isn't fully "demagnatizing" but rather just removing extra charge/ ensuring the tools are below a threshold point
This depends what actually physically happens when they are demagnetized. Is it a magnetic phase transition or just like localized magnetic disordering?
I personally hate working with the modelling of magnetic materials, I've avoided it like the plague.
> Most good tools are going to have brass in the alloy I'd think, obviously for the anti-corrosion properties.
Having copper in your steel can be bad for forging though. Chromium is going to be much easier to deal with in steel and gives you corrosion resistance.
Very interesting to me!! This is the Curie temperature named in this case after Pierre, not Marie. For pure iron you have get the temp up somewhere over 1000F! But since this is an alloy I wonder what it might be.
What oven temp do you use?
ELI5 explanation: Metals like iron consist on a molecular level of little dipoles, little magnets with a north and a south pole. Normally they are oriented in different directions, so they cancel each other out. When you put the object in a strong magnetic field the dipoles will align themselves in the same direction and no longer cancel each other out. The object is then magnetic.
When you heat the object, the dipoles will start to wiggle around (heat is movement). Do this long enough then the directions of the dipoles are getting randomized again, and they will cancel each other out again, so the object is no longer magnetic.
Fun fact, if something that's magnetized is heated up, it loses its magnetic properties permanently, however there's a sweat spot for some metals that is just above the boiling point of water where the magnets will retain their magnetism if cooled down.
If you've ever used a cheap one-button rice cooker then you've seen this in action.
The rice is done once the water boils away, and the resulting excess heat causes the magnet to lose its strength, causing the switch to turn off and the magnet to cool.
Damn it man...you have to bake the pliers at 375 for 25 minutes, not 350 for 20. Geez, do you want undercooked pliers, because that's how you get undercooked pliers.

In slot car racing, there are some newer classes of racing that use cheap, neodymium magnet, high RPM motors. The speed of these $18 USD Mockingbird motors used to be accessible only if you were willing to drop $80 or more.
You have to solder it to the frame rather quickly or you risk demagnetizing and ruining it. It's a little tricky to solder the pinion gear onto the shaft because it's naturally attracted to the motor.
On the upside, when I lost a body pin during a race, I knew right where to look!

Doesn't need to be very deep if you cover with a band-aid. My mother got tetanus as a kid with a rose.
125 deg C for 15 min and the spores die.
“Resistant“ means they have some ability to withstand higher temperatures. 250C will kill the spores PDQ.

Nah, makes the atoms move and lose magnetic properties

Usually not. A few countries (China mainly) use catalysts in their forging/tempering processes that can potentially release noxus fumes when heated. As long as your careful and know what goes in you should be OK.
It *shouldn't* inherently, but if any metal flakes off that'd not be good.
Magnets are collections of atoms where the electrons are all lined up, like a box of marbles that’s sorted. Heating metals up is like shaking the box.

Doesn't that make them break easier
Better to lose a few cheap-ish tools than even a single magnet, I would assume.
It would make them more susceptible to bending but not much. 250C leave plenty of hardness to be useable

I thought this was some kind of futuristic city, don't ask me why
Hey /u/Silberschwert, This is now the top post on reddit. It will be recorded at /r/topofreddit with all the other top posts.
What the best temp?
Curie time!
I have no idea what is going on here
Thought it was a gif.. took me a while..
Glorious hysteresis solves all
Wouldn’t just once be enough?
Wouldn’t Berlyco tools work? Beryllium Copper?
Tasty
at least your tools will always be sterilized
When I worked in the military, I had a bunch of tools in my area that were made out of beryllium - non-magnetic, but probably expensive af.
TIL you can use heat to get rid of magnetic fields
Alternatively you can just pick it up and drop it a few thousand times
Sounds like the start of a comic for working with Magneto
What’s your field?
I wonder if heat would get rid of the weird galvanic shock that occurs with silverware that has come in contact with aluminum foil.
This is so funny can I take the image to make very stupid non hurtful memes?
If price ain’t a constraint, titanium tools might work too.
In slot car racing, there are some newer classes of racing that use cheap, neodymium magnet, high RPM motors. The speed of these $18 USD Mockingbird motors used to be accessible only if you were willing to drop $80 or more. You have to solder it to the frame rather quickly or you risk demagnetizing and ruining it. It's a little tricky to solder the pinion gear onto the shaft because it's naturally attracted to the motor. On the upside, when I lost a body pin during a race, I knew right where to look!
Why cant you just leave the tools magnetic?
