I have talked to the student again.
He wants to direct current through one wire and have the magnetic field of that wire levitate a different wire on top.
He was initially using a 1 kilogram wire, which I was like what kind of wire is that?
He is now going to use a 2 gram wire.
The school's power supply can only supply 6 A.
I am not really sure what gauge wire to use or what potential difference....
