Superconductivity Demonstration Kits
For educational purposes we prepare following low priced kits for schools. All the kits can be used as aids for teaching physics and other subjects.
CSDK 1 - Demonstration kit for Meissner effect
- Basic property of superconductors |
 |

Small rare earth magnet levitating above high temperature superconductor YBaCuO disk cooled by liquid nitrogen |
CSDK 4 - Demonstration superconducting current lead |
 |
Example of applicable superconductivity - current lead to superconducting magnets |
The lead demostrates zero resistance of superconductors. It could be used for measuring AC/DC critical current and AC losses. External voltage taps allow easy handling and connecting to measuring devices. Critical current at 77 K (liquid nitrogen temperature) is about 60 A. Superconducting part is made of BiPbSrCaCuO superconductor (2223 phase), the critical temperature is 108 K. The case is a combination of glass and stainless steel. |
OTHER DEMONSTRATION PARTS
- Parts made of BiPbSrCaCuO superconductor (critical temperature 108 K) |
CSB -2/3/20 - superconducting bar with silver layer on both ends for an easy soldering the current and voltage leads (thickness 2 mm, width 3 mm, length 20 mm) - suitable as a sample for measuring the critical temperature and critical current
CST -10/10.2 - superconducting ring (ID 10 mm, length 10 mm, wall thickness 1 mm)
CST -15/15.2 - superconducting ring (ID 15 mm, length 15 mm, wall thickness 1.5 mm)
|
 |
The rings are suitable as samples for measuring shielding properties of superconductors and as superconducting parts of current limiters. |
