Battery for magnetic levitation
electromagnetic harvesters use a pseudo-magnetic levitation effect [22–24] for energy recovery. Note that magnetic levitation always occurs with a help of a mechanical constraint for stability. The Earnshaw''s theorem proves that it is not possible to achieve magnetic levitation using any combination of the fixed magnets and electric charges.
