Diamagnetic levitation and wetting anomalies.

Lévitation diamagnétique et anomalies de mouillage.

Author(s) : BEAUGNON E., FABREGUE D., NAPPA J., et al.

Summary

Diamagnetic substances can be maintained in the form of a stable suspension without any contact, in the intense field gradient created by a superconducting coil. The authors present video recordings showing the levitation of ethanol droplets with a radius of just a few millimetres. When several droplets are simultaneously injected in the stable levitation zone, the residual magnetic forces tend to gather them together at one point of the field's axis. One then observes a phenomenon that can be reproduced: frequent rebounds prior to coalescence.
