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. With this fascinating kit you can demonstrate both the Meissner Effect and the Suspension Effect.
Includes: a neodymium iron boron cube magnet, a superconductive 1.5 cm enhanced flux pinning disc and a standard 1.5 cm disc made of ytterbium-barium-copper-silver oxide, a samarium cobalt rare earth magnet, tweezers, and a teacher’s guide.
Note: this kit requires, but does not include, liquid nitrogen (which is commonly sold by welder’s supply houses).
