Maxwell's law states an electric field in motion creates a magnetic field. In the mind experiment the wand would be an electric field and the dominoes the magnetic field.
As an electrical potential is placed on a conductor it will create a magnetic "B" field around the conductor. An AC field will produce a B field in one polarity as it goes positive and a B field in the opposite polarity as it goes negative. The fields and motion are at 90 degrees to each other.
So our dominoes would stand - fall - stand in opposite direction.
This is enough for now. More later.......
