superconductores

Superconductors are materials that can conduct electricity without any resistance when cooled below a certain temperature. Normally, electrical resistance causes energy loss as heat, but in a superconductor, electrons pair up and move smoothly, eliminating these losses. This property allows for highly efficient power transmission and powerful electromagnets used in medical imaging and maglev trains. Superconductivity only occurs at very low temperatures, often near absolute zero, though scientists are researching materials that work at higher temperatures to make practical applications more feasible.
