Class experiments for superconductivity and magnetism
Ready-to-run classroom and science-fair experiments: a coin and superconductor drop, Meissner versus flux pinning, force measurement, resistance, and a no-liquid-nitrogen maglev build. Free to use whether or not you buy a kit.
Five experiments you can run this term.
Start with the perfect-metal experiment, where a coin brakes and a superconductor is repelled or locks, then move into Meissner, pinning force, resistance, or a permanent-magnet maglev when cryogenics are off the table.
Is a superconductor a perfect metal?
Drop a coin, then a cooled superconductor, over magnets. Repulsion, locking, and an advanced field-cooled vs zero-field-cooled comparison.
Class time: 30-40 minutes
Meissner or flux pinning?
Qualitative steps that separate Meissner repulsion from flux pinning, plus a path to force numbers.
High-school advanced physics and undergraduate labs
Flux-pinning force method
A science-fair method with variables, field cooling, repeated force readings, and error bars.
Measuring superconductivity
Why 4-wire beats 2-wire, what an R-T curve should look like, and how to catch common pitfalls.
Maglev science project (no LN2)
Build a permanent-magnet train for an ordinary classroom when liquid nitrogen is not an option.

Science fair project ideas
Projects sorted by what students can get hold of, with planning and presentation notes.
Match the experiment to the kit.
Most of the set runs on a handheld magnetic device and a levitator. Classroom sets add stations for group work. Use which kit if you are unsure.
