Solenoid produces a magnetic field when a current is run through it. Field and force points in the positive j vector. The solenoid is broken at the top to keep it from being influenced above it. It's easy, set the weight of the magnet equal to the magnetic field and solve for the current you have to run through the coil.

This is basic electromagnetism.

Wrap a string of copper in a coil and run a current through it, it will create a magnetic field. It was pretty groundbreaking shit when it came out and is fucking insane because it links electricity and magnetism which where hitherto considered completely separate forces. WOAH
But today it's pretty basic science. It's how you make really strong magnets if you want one, rather than just digging up an ore that happens to be magnetic.

>melts the magnet

There is no magnet, the cylinder is made of aluminum. A magnet would soon exceed the curie temp and lose its magnetic flux. The induced secondary field keeps the object in place until the current is switched off, then the liquid alu drops down and solidifies.

Induction heaters (and Lenz-law levitators, this thing is a combination of both) only work on pretty conductive stuff like metal. Dunno if it would do much to flesh. You could put a ring on that finger or a nail in the hotdog and cook it that way though.
