HUGE Magnet VS Copper Sphere - Defying Gravity- Will a Neodymium Magnet Float Inside?

[@Nighthawkinlight]

Really clever idea! You might try painting the copper black and playing with the shutter speed of the camera to get a stroboscope effect that will make the copper look like it's not rotating so fast. Alternately do a really slow shutter speed so the cage is a blur and the sphere stands out better since it moves slowly

[@DVSS77]

The stroboscope effect would be great to look at!

[@terracar2003]

Hey, love your videos! I was curious as to whether or not you have considered making content about the potential uses of thermoelectrics in personal temperature control? Like a air-conditioning suit using that thermal fabric of yours alongside a thermoelectric cooling pad.

[@SeanBZA]

Or put an optical sensor on the drive, place a slotted disk on the shaft, and use a LED lamp, so that the lamp only shines when there is a view into the sphere from the camera. Will need to be optical simply because magnetic will not work with that massive field. Copper sphere would be best also heavily plated with silver, to reduce skin resistance, or of course if it was cast entirely in silver as well, either pure, or alloyed with copper like coins, so you get a harder alloy, but still with lower resistance.

[@dakken74]

You should try a strobe lightand and try to match it to the shutter speed of the camera

[@NapoleonThe12th]

You beat me to suggesting painting the magnet! It's fine, I'm already subscribed to you. I was going to suggest a bright blue paint to contrast with the red copper.

[@matttgray]

7:55 YOU NEED TO CHANGE AXIS OF ROTATION - that slice is disrupting the eddy current / Lenz’s Law, and the orientation is exacerbating the issue. You're rotating the sphere around the poles, and the slice is along the equator. If you move the axis of rotation to the equator, it will allow for larger, more continuous eddy current loops to form. There’s a short titled “Can a non-magnetic material be stopped by a magnet?” by tamuphysastr that overviews this concept pretty well

[@crains8087]

Or have a different design for the copper sphere that allows the eddy currents to form. The structure of the sphere, with all those holes, is limiting the size of the eddy currents. Try a sphere with bands perpendicular to the axis of rotation. I'd also try it with the cylindrical magnet inside the sphere.

[@HB-et5iv]

No rotating over the poles. The magnet will always turn to align its poles with the axis of rotation, i.e. so that it feels the lowest forces. For the same reason it starts rotating with the sphere until the speeds match, the eddy currents cease, and it stops levitating :(

[@skywolfbat]

It's 100% the shape. It's creating patterns in the eddy currents which want to follow the shape of the copper. Remaking the mold with a band like structure (Think a spherical set of jail bars that meet at the poles) might give a better result. Or, if you wanted to have the bars of copper going along the axis of rotation, clip them in a cage like formation with plastic bars running one way and bands of copper running the other.

of have long-enough exposure time to fully blur the sphere at speed

[@robspiess]

The "sphere" has 60º rotational symmetry, so you can multiply that stroboscope by 6 (n/10 fps): 60RPM = 6fps 120RPM = 12fps 300RPM = 30fps And use a short exposure time (with lots of light) so as not to blur the sphere to help it look stationary.

[@jmquadros]

A stroboscopic light at 1/10 the RPM would give a better effect than changing the exposure, it would also be easier to synchronize with the holes of the copper sphere

[@LeonardoG1981]

@@robspiess I thought that if he matches the RPMs to the FPS it should be enough, because each frame would equal one rotation and would capture the truncated icosahedron on the same position every time, making it look stationary, so we should be able to see through one of the openings as if the truncated icosahedron was stationary.

[@jawa7609]

Cast a thinner/Sand down the inner circumference of the chew toy? Make larger holes in the sphere? Weaker magnet? My thinking is the Hall Effect is overwhelming the power of the magnet because of the volume of copper. Even at slow speeds, there's too much resistence being generated by the sheer volume of copper in relation to the volume/effect of the magnet. In other words, Too much flour, not enough eggs in the cake. Try a larger area around the magnet, a smaller magnet, or less total copper around the magnet via larger holes. One/all of them are your solution. Find a ferrous sphere magnet and see what happens! I bet you could do higher speeds purely because of the MUCH weaker interaction between the materials.

You should induce the spin using an external magnet like you did at the end, but using a motor to spin the external magnet. This will keep the magnetic poles perpendicular to the axis of rotation of the cage. The inner magnet would then be spinning the cage rather than the cage spinning the magnet. It should float nicely then.

Actually as it is have many holes , this really reduce eddy cuurent as resistance gets larger in the sphere thing and so the the magnet can not have the suspension force like in a solid cylinder so i think this is the most you can get out of it Also the split between the 2 Half's of the sphere reduce eddy current and increase resistivity as there is a layer of air between them ( even if they are touching it is higher resistant that the copper it self ) But awesome design non the less

Because the sphere is polygonal magnetically the magnet will see a bumpy surface, the join line being down the middle will make it even worse because the magnet only 'sees' loops of copper as electromagnets, and the join line breaks lots of loops of copper which ought to be there. This will make the centrifugal force problem much worse as the magnet is being effectively grabbed by the bumps. I think you could get the effect you want by making the sphere out of a series of copper rings held together by something non conductive. That way the symmetry isn't broken and the ball should levitate smoothly.

For the ceramic being as hard as it is, it seemed like you were just blowing away fluffy marshmallow with the sand blaster. That was very satisfying to watch.

[@rogerd4559]

Yes that puzzled me also. Ive used a sandblaster many times and never had it that powerful to blast through ceramic material like that

Okay, so the making of the sphere was so very satisfying. Well done.

[@RustyInventions-wz6ir]

Wow. Very nice work mister. Very interesting.

[@jkkarkar]

Rotating the copper sphere with the other magnet is something akin to a differential. Very cool.

[@rossbrumby1957]

Magnetic torque converter- could make one with variable magnetic proximity so as to be a clutch/torque converter in one. Good for a gokart.

[@gaersofwar]

A dutch company called Zytec makes an industrial coupling with a magnetic and a copper disk to make a coupling with no physical connection between the motor and the driven part.

[@SashaInTheCloud]

Don't show this to Dyson. We will end up with really odd vacuum cleaners labeled with pacemaker warnings.

[@SanctiFae]

Huge thank you, for making this video! My 50cents: Quench the copper to increase the electromagnetic conductivity, yes this will influence the total size and possibly shape of the sphere, I would suggest doing this in multiple 'soft' stages, where you raise the copper's temperature and then rapidly cool it across several slowly increasing increments to maintain structural symetry as much as possible. There seems to be a definite need to play with lighting and the coloring of the sphere to better showcase the events, I think it would definitely make it look more awesome. I'd love to see you use this sphere in a future video where you showcase some interactions with its unique shape and ferrofluid.

[@AllenKnutson]

Visionary stuff man. Great to see the mix of 3d printing and ceramic preliminaries. 1) Make the interior of the truncated dodecahedron spherical rather than polyhedral. That is, start with a sphere and poke nice holes in it. 2) Once you have a better setup with the drill spinner, match the rotation to the shutter speed so the cage isn't visibly rotating.

[@nelsonfeliciano9717]

Practical use of idea: miniature scale prototype. Hollow Copper tube 10ft long 10inch diameter. Inside on walls of tube place equally spaced negative to positive strips of magnetism equivalent length of copper tube. The passenger capsule will be the ultra powerful spherical magnet. Process of motion. Copper tube is to spin at a constant. Electric current is to run in the strips in the Copper tube. Each end of the Copper tube is to have a repelling force for the magnetic sphere aka the passenger capsule. Thus creating hyper-velocity from point A to point B. Congratulations. You have invented . A new transportation system.

[@luis96xd]

I would love to see it, miniature scale prototype

[@darrylpender867]

Did you just explain the transportation device in the movie, "Contact?"

[@daviddobson1659]

Sounds fantastic in theory, but I'm not sure constantly rotating the road or track to power the vehicle would be very efficient.......😮

[@zekevictor]

That’s crazy and unnecessary… instead of track rotation, come up with something clever like how LIMs do it - electromagnets turning on and off in sequence, or perhaps moving magnets, etc.

Amazing how you made the copper casting. You make it looks so doable and easy. As a mechanical/manufacturing engineer that was my favourite part of this. I just don’t have the drive or will, or patience for this. Not sure how you can afford to do this, but good for you if this channel is making it happen. I can’t imagine doing anything well enough that I enjoy and make money from enough to survive or thrive.

Use a in frequency adjustable stroboscope light in complete darkness while it's rotating. That brings the copper sphere to "stop". Not only for the camera but also for your eyes. Great project, thanks 👍🏻
