After last night's challenge (or inspiration), we levitated our magnet this morning. Since the nice Olympus camera is not currently in the 40m, we had to use my less stellar camera, but despite the poor video quality you can still see the magnet returning to its stable equilibrium position. Once we recover the better camera, we will post new videos. Also, we haven't yet figured out how to put videos in line in the elog entry, so here are the youtube links:
We adjusted the gain on coil 1 so that the resistance from the pots was 57.1k (maximum gain of 101.2,).
currents from power supply, pre-levitation: 0.08 A and 0.34 A
post levitation: 0.08 A and 0.11 A
note: we're not sure why changing the gain on coil 3 changes the current through the power supply, so we'd like to investigate that next.
