Superconductivity Project
Experiment Guide (Colorado Superconducting Kits)
As an introduction to superconducting system, three experimental guides were worked through to demonstrate different properties of super conductors. Below were the experiments conducted, before advancing to the mr. SQUID kit.
Lab one: Messner Effect
Definition: The expulsion of magnetic flux when a material becomes superconducting in a magnetic field. If the magnetic field is applied after the material has become superconducting, the flux cannot penetrate it.
The goal of this first lab is to show that this is true.
Observations: As the system dips below the critical temperature the magnet levitates. The magnet can then be sent into rotation, which in a perfect environment would rotate forever due to its frictionless property. The system increases in temperature due to the room, and will no longer levitate once it passes the critical temperature.
