This kit allows the experimenter to accurately determine the Critical Temperature of a superconductor by measuring and plotting its magnetic susceptibility against temperature. Includes the new and innovative Susceptibility Probe developed by researchers at Whittier College, a 100 ohm resistor, plus a one-inch YBa₂Cu₃O₇ superconductor, rare-earth magnet and non-magnetic tweezers for Meissner Effect demonstrations.

This revolutionary new kit allows the experimenter to accurately determine the different Critical Temperatures associated with the bismuth based superconductor by measuring and plotting its magnetic susceptibility against temperature.  Based on the K20 kit, the bismuth superconductor is a composite of two separate superconducting crystalline phases.  The Bi₂Sr₂Ca₂Cu₃O₁₀ superconducting crystals that have a critical temperature of 110K, and the Bi₂Sr₂Ca₁Cu₂O₉ superconducting crystals that have a critical temperature of 85K.  This kit includes a Bismuth Susceptibility Probe, a 100 ohm resistor, plus a one-inch Bi₂Sr₂Ca₂Cu₃O₁₀ superconductor, rare-earth magnet and non-magnetic tweezers for Meissner Effect demonstrations.
