So this kind of scaling up does not in itself lead to a solution, but it means that once you have a solution (i.e. magnetic force larger than gravitational), you can immediately use it to make a bigger device by making all the wires longer, and thus support a heavier load. | |

I think this because although there is a lot of current, that is, a lot of electrons moving, they don't have much kinetic energy, as there isn't a big potential difference pushing them. | |

The more conductors used, the less force each one needs to make alone, so the less current in each conductor would be needed to levitate something. However, adding more conductors would increase the weight of the entire apparatus. | |
