Source is YouTube and Institute of Chemistry and Chemical Technology SB RAS (PDF). If you have 2 kilowatts, a coil of copper pipe, and a lot of guts, you too could melt aluminum with induction heating while it's levitating.
Aww, I wanted to see it splat into the floor when they turn off the induction coil...
I always thought it fell when it got so hot that it lost its magnetism I'm sure I have read that metals do that at too high temperatures
I believe it’s suspended by eddy currents, not magnetism. Aluminum is a non-magnetic metal.
Indeed.
Despite my own work in making knives and other blacksmithing things, where I LITERALLY have a magnet on my anvil so I can test for when the steel hits it's austenitic temp, I somehow managed to forget the iron will go non magnetic...
So yeah. Thanks for the reminder!
In my defense I haven't made any knives since moving a year ago...
However, this is aluminum I think? I'm not entirely sure how magnetism works with lenzs law and if there's a temperature it stops working...
FYI, you can see that in the source, which is linked in the description.
