http://www.ted.com/talks/eric_giler_demos_wireless_electricity.html In this video, I have two questions: 1) Why have a capacitor as part of the two circuits? Is it so no actual current flows around the coils, that's all I could come up with. 2) In the picture he shows of the two conductors joining at resonance, why does the magnetic field of the bottom one point in the same direction as the top (source) coil? Wouldn't we expect them to oppose each other like two bar magnets anti-aligned since Lenz's Law would say the induced electric field points clockwise viewed from above in the bottom coil? Thanks!
