But, there may be another way, albeit a rather special case, where a magnet can not only be levitated, but locked in place using a rotating magnetic field. The video shows a demonstration of how ...

Earth’s magnetic field is generated by the spinning ball of molten iron at the planet’s center. It performs a variety of important functions, including acting as a shield against solar winds.

And while this magnetic levitation motor does not break ... It’s not a motor that can do any useful work, spinning at a stately pace beneath its bell-jar enclosure as it does.
