This multi-phase kit lets students precisely measure the electrical resistance of a superconducting material as a function of temperature; determine the critical magnetic field that destroys the superconducting phase; measure the maximum, or critical, current that the superconductor can carry; and demonstrate the Josephson Effect and the Meissner Effect.
Includes:
Superconductor with a built-in,
Four-point electrical probe and thermometer,
A 2.5 cm diameter superconductor disc,
A cubical neodymium rare earth alloy magnet,
A cylindrical samarium rare earth alloy magnet, tweezers,
A container for a liquid nitrogen bath and a teacher’s guide.
