A superconductor is a material that can conduct electricity with zero resistance below a certain critical temperature.
What is the Meissner effect?
The Meissner effect is the expulsion of a magnetic field from a superconductor as it transitions into the superconducting state.
Why are superconductors important for power transmission?
Superconductors can transmit electricity without energy loss, making power grids more efficient and reducing waste.
What is a critical temperature in the context of superconductors?
The critical temperature is the temperature below which a material becomes superconducting and exhibits zero electrical resistance.
What is the difference between Type I and Type II superconductors?
Type I superconductors exhibit zero resistance and expel all magnetic fields in weak magnetic fields, while Type II allow partial penetration of magnetic fields at higher fields.
