How does superfluid helium-3 affect magnetic fields?
Magnifies them
Nullifies them
Does not affect them
Expels them
Answer
Expelling magnetic fields is a unique property of superfluid helium-3. When cooled to extremely low temperatures, helium-3 enters a superfluid state where it exhibits unusual properties. One such property is the Meissner effect, which causes superfluid helium-3 to expel magnetic fields from its interior. This occurs because the superfluid's Cooper pairs, which are pairs of helium-3 atoms, form a coherent state that is unaffected by magnetic fields.
