Description: Students measure the electrical resistance of a normal conductor and a high-temperature superconductor (Bi-2223). They study the Meissner-Ochsenfeld-Effect and the Flux-Pinning-Effect.

Safety: Liquid nitrogen – used in the experiments – has a boiling point of approx. -196°C (77K). Liquid nitrogen will be distributed only by S'Cool LAB tutors. Some of the magnets used are very strong and must handled with care by the students.

Availability & age recommendation: 

• Can be included in S'Cool LAB PLUS+ programmes.
• Minimum age: 17, recommended age: 17-19
