There is an idea, for the implementation of which it is necessary to create a small electromagnet that can "repel" and "attract" a small magnet (neodymium) in the form of a cylinder 1mm in diameter and 4mm in height. The question is what size the coil should be and how much it can consume so that it can lift such a magnet for several minutes without melting.

Disassemble some kind of relay, just what you need.
