Is there a weight limit for magnetic levitation?

Let’s get the answer first: Theoretically, no.

As long as making big enough magnets and electromagnetic coils, there’s no levitation weight limit. However, in order to make the price acceptable and reasonable, the weight limit of top levitation technology is 20kg maximum. The weight limit of bottom levitation technology is 4kg maximum. Because this is the biggest magnet size which is available and existing in the market. Otherwise, we have to customize the huge magnet which costs a lot of money
