Tesla talked about veritable ropes in the sky when he spoke of his flying machines, he was talking about being lifted via a mechanism.
You have obviously studied this picture, I will draw your attention to Pancake coil item J. on http://i0.wp.com/www.truthinsideofyo...size=700%2C524 you posted.
I have played with high power, years ago, on an unrelated subject, but did note cables on wooden benches ie none magnetic surfaces. Would lift of the surface of the bench on the rising edge of the the current. Subsequently I have wound flat pancake coils and pulsed current through them out of curiousity, if the current is pulsed in the right direction they do move, I have not built anything serious to investigate this phenomina yet.
Ref your conjecture that gravity is caused by magnetism, I partly disagree with you, for various reasons which I documented in my essays. I donīt know if you bothered to read the updated version of gravity I wrote. I mentioned using a pancake coil to create an antigravity device, it might be better used to make an area of reduced density space, that would attract something, ie stretch space above a capsule, rather than repelling gravity. Create another gravitational field in the direction you want to go.
A Pulsed magnetic field could affect space the ether what ever you want to call it, and make it less dense, space has inertia if it can be stretched by a mass (made to vibrate) it coud equally be stretched by a magnetic or possibly electric field operating at high frequency.
