I'm looking for a magnetic levitation module that can hold a small and light object, around 30-50g. I'm looking for modules that work by holding an object from above like a levitating globe but also one that work from the bottom up like a levitating lamp or flower pot. I just need the module, no housing, because it will be put inside an individual object. It's also crucial that the levitating magnet or metal plate is as small as possible. I'd like to know the smallest diameter or size of the levitating object because it needs to be put into another small and light object that will float in the air.
