5G30.35 - Liquid Oxygen and Nitrogen Beads on Magnetic Track
Show how oxygen and nitrogen flow on a magnetic track
Set up the elliptical superconductor track, a bench rod with cross clamp and the copper cone from diamagnetic oxygen so that the cone can be swung over the track. A camera is needed to image the beads moving on the track. Also be sure the nitrogen gloves and paper towels are with the set up.
To view the oxygen fill the cone with liquid nitrogen while it is above the lecture bench. Then swing the cone over the track so the drops fall a little downhill from the middle of a sharp curve on the middle magnet. Beads should drip off the cone and flow down the track.
To view nitrogen, while using the liquid nitrogen gloves, dip a paper towel into a small nitrogen container taking care to only dip the towel, not your fingers. Shake off excess liquid and hold the paper towel above track. Watch as the beads act like the oxygen did and move along the rails of the magnetic track.
