Study Notes
Superconductivity Discoveries
- In 1911, Kamerlingh Onnes discovered superconductivity during low temperature measurements.
Superconductor Behavior
- A magnetic field or high transport currents can cause a superconductor to enter a resistive state.
Meissner Effect
- The Meissner effect is the expulsion of magnetic fields from a superconductor when it is cooled below its critical temperature (Tc).
Superconductor Properties
- According to MCP | RIDHIMA GAHROTRA, the more fundamental property of superconductors is perfect diamagnetism, which is more fundamental than zero resistance.
Superconductors and Magnetic Fields
- When T < Tc, superconductors expel magnetic fields, a phenomenon known as the Meissner effect.
