Superconductivity is the spectacular characteristic of the total disappearance of electrical resistance when a superconductor is cooled below a critical temperature. Another important and unique property of superconductors is that if a magnetic field is applied to the superconductor, the effect of magnetization can be reversed. This reversible magnetic behavior is called the Meissner Effect. It is this Meissner Effect that would enable a train to levitate above its tracks. Since there would be no friction between wheels and track, the train could operate while consuming very little energy.
This unique demonstration kit will provide you with all the materials needed (except liquid nitrogen) to successfully demonstrate the characteristics of superconductivity and the Meissner Effect. Each demonstration kit includes one rugged 1" superconductor, one rare earth magnet, one non-metallic forceps and one “how to” instruction manual.
