Use a real ceramic superconductor to demonstrate the Meissner Effect (that a material in a superconducting state will repel a magnet), and determine the critical temperature (Tc) with this inexpensive kit. Kit includes a well-written 16-page booklet containing instructions, background information on superconductivity and guidelines for safe use of liquid nitrogen. Requires the use of liquid nitrogen, commonly sold by welders’ supply houses.
This kit allows you to determine that the critical temperature (Tc) of the superconductor material is about 93° Kelvin. It features everything included in the Complete Demonstration Kit, plus a 1.5 cm diameter superconductor with thermocouple, and instructions for use.
Note: You will also need a digital voltmeter to perform the critical temperature experiment.
