Superconducting Quantum Interference Devices

Superconducting Quantum Interference Devices (SQUIDs) are highly sensitive instruments used to measure extremely small magnetic fields. They consist of superconducting materials that allow electric current to flow without resistance. SQUIDs exploit quantum mechanics, specifically the interference of electron waves, to detect magnetic flux changes. This ability makes them valuable in various fields, including medical imaging (like MRI), materials science, and fundamental physics research. Their sensitivity enables researchers to observe subtle magnetic phenomena that would be undetectable with traditional instruments, paving the way for advancements in technology and science.
