Measure the critical temperature (Tc) of a high-Tc superconductor with this easy-to-use intuitive and educational kit.

• Four-point Tc experiment

The four-point Tc experiment is the basic and most educational experiments in superconductivity and experimental physics. The kit allows students to measure the electrical resistance of a superconductor bar using the two-wire and four-wire configurations.

The setup includes a high-Tc superconductor Bi-2223 bar with four contact points. Four wires are physically attached to the superconductor allowing both a four-wire and two-wire resistance measurements. The superconductor sits on metallic plate that serves as a thermal equalizer and includes a pt-100 resistance thermometer.
