Damn! I knew there was iron in cereal, but I didn't know you can get it out. Thanks!
Yeah, actually I've been thinking about doing this too for a while. It wasn't until I saw your question that I actually got the initiative to research how to extract the iron.
Thanks, I guess...
Please note: I'm a bit crazy. No I'm not! Yes you are! I'LL SHOW YOU CRAZY!
*rolls on floor, punching and biting self*
Transformers! you probably have at least 20 of them lying around.
a transformer is basically a lump of iron with lots of copper wound around it.
old plumbing pipes should work as well.
Well I think your very lucky! Not that many people have 20 giant alien robots that turn into cars lying around! ;-)
XD, i was talking about the more boring kind of transformers.
but sure, you could probably use the other kind as well ; )
LOL! In the middle of the night " hey optimus, turn around for a second " *grabs bench grinder*...
You might actually. If i remember correctly, things like phone charges, laptop power packs and computer power supplys.
i forgot about car brakes!
a few weeks ago, my father changed the brakes on our car and i noticed they where full of metal dust, i checked with a magnet and sure enough! it's iron :D
Pure iron metal is not the only thing that sticks to magnets.The magnetic field viewer that Frollard is referring to is described here:https://www.instructables.com/id/3D-Magnetic-Field-Viewer/
dose it have to be iron of can it be steel
It needs to be iron
it's a heck of a lot more work to make iron filings than it is to buy them online. I know its not what you wanted to know, but really I speak truth. As vince suggested steel wool is mostly iron.
What's your project?
Well, iron filings align with magnetic fields, and I have a ton of magnets I want to fool around with to see the difference.
scissor up some steel wool, then put it in a bottle of mineral oil. It works the same - and shows the fields (even better than just filings)
your best bet is to look for cast iron, if it will work. finding it is easy if you have a shop look for rather big heavy parts that look kinda bumpy. the older the better the older it is the more likely its cast iron they are goin to more aluminium stuff now. but look for bell housings gear boxes transfer cases differentials engine blocks thats the most common cast iron items that come to my mind
You might try magnetite instead?L
really depends...theres old cast iron fire places, u can get iron piping,u can get iron grills.
