who was it that said, i make a train in a tunnel, my coil. i use a tesla secondary. i aim it north and south. i use a gauss gun to launch a magnet through this tunnel, and wait for my output.
then i make a train, the return trip is south.
i make it go forever.. close to forever.:P:cool::D
glass tube secondary coil. round magnet. right through the center of my tunnel. very fast indeed.
adv, even then i make my magnet as the track, an edd lee long electric magnetic pmh. like in book. south pole outside, north inside.
imagine..:D:idea::idea: even then i use the magnet itself, and add a glass tube down the middle.
