Creating an electromagnet as powerful as an NeFeB magnet with same size Answered

Is this possible?

So I'm working on this project on levitation using superconductor and strong NeFeB magnets. I'm try to determine the possibility of replacing the magnets with electromagnets equally as powerful and of the same size if not smaller. But I'm bit skeptic about the idea as I'm not sure how possible it will be to construct such electromagnet (or buy them preferable). Is this something that is possible? can anyone reading this give me recommendations? thanks

If you stay in super conductors make an enhanced low heat magnet coil that eliminates I2R

I squared R losses in two ways..

This technique Will produce the same electromagnetic pull force at a lower current !

This allows lower heat I^2R rejection :-)

The cost is a small current needs to drive the coil in reverse to achieve zero magnetic flux..

Consider it a bias PM Enhanced Electro Magnet.

This is just what I remember from 8th grade science but theoreticly it is possible but you would need to reset your object every time you turn it on. It would also be quite hard to make the magnet otherwise if you where to bye it it would be quite expensive. I would research a bit more about the pros and cons
