SK053 Superconductivity Experiment Kit

Superconductivity Experiment Kit  Meissner effect, the expulsion of a magnetic field from the interior of a material that is in the process of becoming a superconductor, that is, losing its resistance to the flow of electrical currents when cooled below a certain temperature, called the transition temperature, usually close to absolute zero. The Meissner effect, a property of all superconductors, was discovered by the German physicists W. Meissner and R. Ochsenfeld in 1933. Features: Bismuth superconductor with four probe arrangement & thermocouple. Voltage probes for temperature & voltage measurement. Data logger with 100k samples per second capacity. Data Logger with 6 built-in sensors Free data analyzing software. Objectives: To demonstrate meissner effect. To measure the transition temperature of a high temperature superconductor.
