400MHz Oxford superconducting magnet Quenched by opening the vacuum valve to a little helium gas. It filled the ceiling with helium gas boil off from probably about 40 Litres of liquid helium.

[Question from NMRWiki Q&A forum] Is it safe to do levitation demo with superconducting NMR magnets?
Is it safe to do levitation demo with superconducting NMR magnets?
We do this trick with our 800 MHz Oxford Instruments-built magnet often to impress some folks:
Remove the probe and plug bore of the magnet with a rubber cork. Take a donut-shaped disk made of aluminum, put it right under the magnet an let it hang there and slowly fall to the ground.
My question is - can field induced by moving an external conducting object like that disk affect the superconductor and cause a quench?

More tricks using an 11-Tesla superconducting NMR electromagnet. These are used for chemistry research; for determining the detailed shape of unknown molecules using "two dimensional nuclear magnetic resonance."
