Kit of strong levitation force

Example of superconductivity application

Easy manipulation of a 0.1 kg superconducting magnet levitating and flying above a high-temperature superconducting cooled by liquid nitrogen, demonstrating the powerful forces between a NdFeB permanent magnet and a YBaCuO superconducting levitator. The kit also includes accessories for demonstrating the Meissner effect.

Meissner effect disc

The Meissner effect disc is prepared in such a way that the trapped magnetic field is very weak and the Meissner effect then dominates over the trapped field. Therefore, this Y-Ba-Cu-O disc for demonstrating the Meissner effect is made of polycrystalline material with low critical currents.

Disc for demonstrating high levitation force

On the other hand, the disc for demonstrating high levitation force (demonstration of inertia flywheel, etc.) is prepared to allow the passage of high critical currents and the trapped magnetic field is high and dominates over the Meissner effect. This is achieved by preparing the Y-Ba-Cu-O disc as a single crystal of high critical currents.
