Instructions for use
The demonstration kit includes:
- YBCO-123 polycrystalline disk, diameter 22 mm
- small NdFeB magnet, diameter 4 mm
Place the small magnet on top of the YBCO disk.
Pour a small amount of the liquid nitrogen
into the cup until the superconductor is fully immersed.
After approx. one minute the magnet will
float above the superconductor’s surface
demonstrating the magnetic flux expulsion
from the superconductor. Enjoy!
Keep the superconductor in the superconducting state by occasionally pouring the liquid nitrogen. Using tweezers, try to press the magnet to the
superconductor’s surface and/or move it above the superconductor surface. After finishing, let the parts warm to room temperature and dry them properly before storaging.
