Is there a way to make magnetic gloves coated in liquid nitrogen to control metal? Answered

I know that you can make some metals float by coating the magnet in liquid nitrogen. How can I make a pair of magnetic gloves and will my idea work?

First, you have to be bitten by a radioactive spider...

No, it won't work. The most obvious problem is the "coating". The boiling point of nitrogen is 77K. Either your gloves are maintained with an active refrigeration system at 77K, in which case your hands shatter and fall off the ends of your arms; or they are pretty close to your body temperature (~320K) and the liquid nitrogen evaporates away.

Well would it worked with electrically-charged neodymium magnets?

Magnets are neat, but they're not magic. Think about what you want to accomplish and ask about that.

Also, check out by comment on this Answer, particularly the part about Earnshaw's Theorem.

They float a permanent magnet on a ceramic disk by cooling the disk with LN2. The ceramic becomes superconducting, and bringing the magnet near induces currents in the ceramic at 'no' resistance, creating an eddy current that opposes the magnetic field, levitating the magnet. As for gloves + manipulating metals...that would be...a feat.
