I was wondering if diamagnetism can be created electrically or does the material have to be diamagnetic in nature?

I'm thinking about a hovering magnetic sphere but neither bismuth or pyrolytic carbon is strong enough. Maybe a copper coil would somehow do the job better. As liquid nitrogen can not be used no superconductors are used.berkeman said:Welcome to the PF.
You mean just to be repelled by a magnetic field? An electromagnet can do that, given the right geometry for the setup. What do you have in mind?

See the video in post #9 of this thread. https://www.physicsforums.com/threa...w-moving-piece-of-metal-static-magnet.924786/ This diamagnetic effect is the result of a changing magnetic field (from the falling magnet) so that tremendous electron currents occur in the copper, generating a magnetic field that repels the floating magnet. The diamagnetic effect in the static case, without a changing magnetic field to create the EMF that generates the currents in the copper, is very small, so that there isn't a static levitation, but it's interesting how the magnet floats down, instead of falling quickly.

Oh thank you! Now I see what you mean.Charles Link said:

As you can see in this: video, the magnetic field can get extremely strong so I believe I have found what I'm looking for. Thank you everyone, best regards Carl.
