If you add salt to liquid nitrogen,would it turn into a superconductor?

I was wondering also if you put a magnet above it, then lifted the magnet up,would the nitrogen and salt come up too?

Unfortunately not. Only a few special materials become superconducting at LN2 temperatures and salt isn't one of them.
In addition superconductors aren't attracted to magnets - they tend to repel magnetic fields.

Adding salt to liquid nitrogen would not turn it into a superconductor. Superconductors are materials that can conduct electricity with zero resistance at very low temperatures, usually below -200 degrees Celsius. While liquid nitrogen is a very cold substance, it is not cold enough to reach the necessary temperature for superconductivity.

As for the question about lifting the nitrogen and salt with a magnet, it is unlikely that the nitrogen and salt would come up with the magnet. Liquid nitrogen is a diamagnetic material, which means it is repelled by magnetic fields. This means that it would not be affected by the magnet and would not be lifted up with it. Additionally, salt is not magnetic, so it would not be affected by the magnet either.
