The only thing you need to copy this experiment is some aluminium foil and a very powerful magnet.
I happened to have access to a 1.0 Tesla MRI system.

  • indeed the 1 Tesla open magnet from Philips.

    It is superconductive (cooled with liquid helium)

    The magnet field points upwards (north pole at the top)

  • Kas, we are waiting next clips:))

    ugur

  • I've got a few more, but they still need to be processed ...

  • hey is their any way to turn a mri machine off ?

  • sure: connect the power supply and reduce the current to zero amps

    or press the emergency button (the magnet quenches and looses the expensive helium)

  • I was traveling in China and they have blocked the connections to YouTube in all the hotels, so I could not reply earlier.

    But: No it will also circle. Next week I'll record a better quality video and update this one

  • Is this example of "quantum levitation", i.e. magnetic flux trapping?

  • fucking magnets.... how do they work?

  • This is a great video

  • @utubesqueeze No. The aluminum is not a superconductor. There is no Meissner effect here. This is merely Lenz's law demonstrated with an extremely powerful magnet.

  • Magnetism is so bizarre but because we're exposed to it as little children we're totally unimpressed by it as adults.

    I mean just look at that video, the piece of metal is floating around in the air like it's no big deal because it is near the other piece of metal and that's just what magnets do... What is this, The Lord of the Rings? It's goddamn sorcery I tell you.

  • Its a verticle (high ) field open MRI with 1T Tesla strength. Actually near the bottom it is close to 3T but they don't mention that ;)

  • That guy is totally high
