The Lorentz Effect is what slows a magnet - while it drops through a conductive tube, such as copper or aluminum. However, it is also the reason that an autonomous Tubular Linear Induction Motor - doesn't move in 1 direction by itself (not attached to rigid ground). The physicists at...
I am an independent scientist. I am working on a way to offset the Lorentz Effect in my projects - using fractal-based twisted-pair windings in a transformer.
