hey, this is very interesting! but i wonder, is it possible to do this just like the Pyrolytic Graphite experiment? only you use bismuth in stead of the pyrolytic graphite, or is that to heavy or something?
Cool Stuff i will order something from ebay, thats for sure!
Hello and good question I pondered the same thing and found out that if you make the bismuth very thin its too heavy and also when very thin does not have the diamagnetic feild strength due to not enouf mass of matreial.
I will include this information in a vid as I made a part over three years ago to find this out.
Thankyou for showing the curiosity required to do this kind of work I like to see when peoples brains work.
Awesome! I have 4oz. of Bismuth Metal "Needles". I know I can melt it down in a crucible to make discs, but I don't want any oxidation to take place. Also, Bismuth is actually slightly radioactive, although, even with a GM Counter, you cannot get a reading, even with an alpha sensitive mica probe, since it's half-life is ~19 Pentillion years! Also you'll have interference with background radiation, (cosmic, radon, trace isotopes, etc.) Awesome diamagnetic experiment! I'm going to try it! 5/5!
Experiments or displays can be set up with one lower plate or one upper plate but both of these setups the magnet can fall out of or get pulled into the upper feild and crash into the lifting magnets I have killed many magnets doing this.
By using two plates you get an upper and lower diamagnetic feild at the same time this means larger levitation gaps or set with a med size gap with two plate is very stable good for hight speed rotation of levitating magnet.
Bismuths radiation is so low if you tryed to test for it in out side in sunlight you would never find any due to all other kinds of radiation that all around us.
Its extremly safe you could live in a house made of it all your life and not die from radiation sickness.
Safety first as a 10mm square magnet spun up with a drinking straw gets over 10,000 almost straight away and if it falls out of feild and one of the square edges hits something solid all the spinning force gets converted into linear.
I've had 5mm square magnet at over 25,000 rpm fly of travel 3.5 meters and bent a plaster wall and fly back at me.
5mm square magnets have little mass but made deep impretion in wall and large noise on impact.From this day I started using safety glasses
Good call! I won't claim to understand the mechanics of this experiment, but I could see how a piece of metal spinning around really fast while being suspended between two rare earth magnets could cause some problems. Play it safe, you guys!
Hello sorry about 3:52 I should have said what I was doing at the time. I lowered the top magnet to get spinning magnet to touch bottom plate of bismuth to stop it from spinning.
Sorry I can't explane the transformers interaction better was thinking of one of your vids when I had the idea you may better explain the rotational effect than me. Please do if you would like all input appreciated.
Yes in time we may explore this more with some experimentation but not until other work is finished first then may cast a bismuth box and try or build with pyrolytic graphite as they simmilar propertys. But for now I'll just look on the web and see what I can find out
Very interesting video. How much of a difference of levitating distance would you say there would be between a piece of pyroytic graphite and bismuth of the same size? The halogen light experiment is very cool, i'll have to try that out.
Thanks for watching we use bismuth for this product becuse or its low melting piont and high diamagnetic propertys.
Also the used face can be polished to a highly reflective suface.
We also sell a product called (Pyrolytic Graphite) It has a higher diamagnetic value than Bismuth and is more expensive. And can not be polished the same as it has a black finish.

Hello, very interesting thing I was wondering if bismuth may also serve as a magnetic shield between the two neodin magnet
Thank you for your reply and wish you a nice day
neja2402 1 year ago
Hello yes Bismuth can be used as a magnetic sheild provided the feild strenght does not saturate the bismuth with too much flux.

Have you tried to create a radiometer by painting alternating white / black
sides of the levitating magnet and using a high intensity light source?

Thank for watching and having a go your self
To avoid oxidation best to slowly heat metal and only just liquafy the more heating over the melting piont the more oxidation you will get.

So why would you need two bismuth plates if one seems to do the job just fine?

Spinning forever would not be taking into account the loss of the magnetic field produced by the magnet. But yes hypothetically. Um yep. Ok

do this in a vacuum!
angryflan 2 years ago
That's what I keep telling people! Since a vacuum will relieve the experiment of air resistance, hypothetically it should be able to spin forever.
I like how you can hear the excitement in his voice as he kind of giggles when he says 10000 rpm lol
xkwiptwendl 2 years ago
Hello I'm hopping to have an answer of some kind this year as to the vac chamber and longer spinning question
My gess is much longer spinning times but there will be like a magnetic dragg effect that will slow it over time.
If not WOW
PS the longest I've had a magnet spin down from hight RPMs 87,000 and took about 49mins
Similar experiment in my other Vid
Levitation at 50,000+rpm
Shows magnet speeds slowing down at timed intervals.

Bismuth is slightly radioactive, sending out Alpha particles, its not dangerous but if you ingest it....

lol , bismuth is litlebit radioactive

Hello as far as I'm aware yes but so low is the radiation that its almost impossable to detect under normal conditions..
Bismuth In its normal state is very stable and very safe and sometimes is used as part of radiation sheilding in industry.

Are you still selling these? I couldn't find them on ebay.
StaceyC123 2 years ago
Hello Thanks for watching.
Yes still selling the (Bismuth Plates)
Its one of our best sellers to date.
Relisted within 6 hours of being sold.
Just search E-Bay for (Bismuth Plates) Still sold for under $50 AUSD
Enjoy.

At 3:52 there is a phenomenon happening: the little cube, in decreasing of velocity, touch the bismuth plate! What might be?
Good your explaining of the tranformer magnetic field influence on the magnet, I like it.
Bye bye

Ok! I understand 3:52
There are several existing studies that illustrate similar interaction of AC with simple metals or magnets.

more soon.

Good question at this time don't know the answer but will look into this more and try to find out but don't think it can be used as sheilding.
