One of our most popular kits, the Complete Exploration
Kit contains the unique Four-Point Probe system -- a
one-inch diameter superconductor disk encased in a brass fitting
with attached current, voltage, and thermocouple probes, allowing
for complete and accurate measurements of several critical
properties of superconductors. Included are two rare-earth
magnets, non-magnetic tweezers and a separate superconductor disk
for Meissner Effect demonstrations.
