This is a repeat of my previous question answered by Bart Broks. He didn't
understand the system I described. Please assume that you have a rectangular
coil (its plane is horizontal) and you put pairs of Helmholtz coils on its sides
(4 pairs, one pair on each side) with their plane vertical.Also, all coils are
mounted on a chassis.Now assume that we can feed this system with enough
power.The result would be four Lorentz forces (one in every side of the
rectangular coil) on the same direction (upwards). Could we say that the Lorentz
force that is exerted on the rectangular coil (caused by the Helmholtz coils
magnetic field) can be used for propulsion? Does action-reaction prevent this
from moving? I know that you have tons of questions to process but please
re-process my question. Thank you!
