  1. the camera is upside down and there’s a magnet above the steel plate they seemingly are standing on (they are actually hanging from it)

    alternatively, the camera is not flipped, and there are magnets on both sides of the plate (below and above but out of sight) the one above keeps the structure standing up, the on below keeps it from lifting up

  2. The wire connected to the nail has an electrical pulse that passes through the nail, creating a magnetic field. The field attracts the magnetic balls.

Makes no difference that it is copper it is the current that results in the …

I suspect it would behave the same with the electricity turned off like this.
