New Product From AVA Magnetic Levitation. Australia pty.
Polished bismuth plates under $50 AUSD the plates come in a pair combined weight is approx 300 grams comes with instructions of care and basic plans to build a Diamagnetic suspention levitation display/experiment. Now also 1X rear earth magnet 6mmX5mmX3mm
gradeN46 Its the same as the one used in this Video to make the levitating magnet spin using the power from a lamps tramsformer. Manny different setups can be done with just a basic display rig like the one in this promo that was built from the basic plans provided with this product. the rig was built in less than 2 hours at a cost of less than $12 AUSD also the height of the levitation depends on the strenght,size,shape of the top magnet and the size,shape and strenght of the magnet to be levitated so all these factures are up to the builder to select. But a good bacis rule to follow when picking magnets for a Diamagnetic suspemtion levitation rig is (Large ferrite ring magnet for the lifter and small rear earth magnets for the levitation )This combo always gets good resaults sofar we have been able to levitate a magnet over one polished plate almost as hight as its own hight.
We hope this product meets all the expectaions of customers requirments as much work has been done to get this hard to work with element to this high quality state and we are committed to further improvments to this product and all our others all the time and will soon have finnish the testing of the thin hard clear coating on the plates this will be offered as on optional extra if required.
Thank you for looking at something new from AVA Magnetic Levitation. AUS.pty
Next Vid ( Late Night Levitations 2) Out very soon also web site soon to be finish with direct sales and retail supply service.

  • 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.

  • 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

  • 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?

  • Doing this work now and will post in a vid in 2 days time

see all

  • Thankyou for that I did'nt know and you have encourage me to learn more on this

    Thankyou again

  • 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.

  • 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!

  • Thank for watching and thinking

    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.
