Your idea for the creation of a magnetic bearing is great. I was wondering what the thickness of the upper and lower magnets were? I was going to try and replicate your idea for my Zamboni battery Devices. My biggest problem has been that the sapphire bearing that I am using will actually dull the point of the steel needle over time. Once dull, the Device will stop. Your bearing would solve that problem completely. I also like that the magnets are all captured. They can't fly off and cause problems.
Good luck. The "bearing" is quite unstable and sensitive to temperature. I have no idea how thick the bismuth layers have to be, probably much thinner than I used.
I was curious about the thickness of the top and bottom magnets. How thick were they? I didn't know that the bearing, even when set up correctly would fail just due to temperature. Is that what you are saying?
Really magnets? Why? It has no meaning... 2mm and 2.5mm, exactly these: www.unimagnet.cz/91-magnet-KR-12-9-02-N.html www.unimagnet.cz/220-KR-17-06-03-N.html The magnetic field of permanent magnets changes slightly with temperature, and this setup is very sensitive. I did not investigate what temperature range is O.K., but you have to take it into account.
Forgive my lack of clarity. I was referring to the thickness of the magnet that rotates, and the lifting magnet above. You answered my question with your reply. I was going to try 6MMx 25 MM Pyrolytic graphite sheets instead of bismuth. I want to float a thicker magnet and try to use it as a low friction bearing. I love your innovative idea to use a ring magnet on a copper rod. That way the magnet never flies off. That is brilliant. Thank you.
The idea about bismuth is good but design of the device is wrong. It uses long bolt that stabilize circular magnet in space. The magnet is touching that bolt as it ax and that makes tiny friction. Whatever is suppose to elevate can not touch anything that stabilize its position in space. It can be done with bismuth and simple design.
@@mm0063 you should try a bowl shape so that the magnetic stabilization comes from a 45 degree angle and not the verticle. That way you don´t need the center rod. If the magnetic field either pushes or pulls towards the center it is kept centered. You always want one lifting magnetic field and one alignment field. You can use the same magnetic field with clever design or you can use one lifting magnet and one ring magnet around the outside pushing in equally from all sides.
Wow! This is fantastic. Thanks for documenting your efforts. I ordered 2 kg of bismuth yesterday. Your video gives me lots of ideas of things I want to try. Thanks again for sharing your efforts.
Really creative implementation, I like it!
Very nicely done video. Love the design and all the visualizations. Hats off! Have sub :)

The center bolt is made from brass. It has no effect on the magnetic field.
Спасибо классно.
This would make a beautiful frictionaless flywheetl if you connect an annular gear to the outer edges
Actually, that might be useful in certain situations. Any time you wanted to test for small air movements like drafts, maybe measure them.
Amazing!
Bravo , extraordinaire et bonne continuation.

very cool thanks for th@

How much Kg or pound bismuth metal u r using?
About 0,012 kg.
@ 4:00 What is the red rod made of? Why did it spin the washer?
That is a straw. Because I blew into it. :-)
nice toy i might be better if 3d printed
