Ultra-sensitive magnetometers

Ultra-sensitive magnetometers are precise devices that detect extremely small magnetic fields, far weaker than those produced by everyday objects. They work by measuring tiny changes in magnetic forces, often using advanced techniques like quantum sensors or superconducting materials. These devices are essential for applications such as geological surveys, detecting underground minerals or tunnels, monitoring brain activity in medical imaging, and studying space phenomena. Their high sensitivity allows scientists to observe subtle magnetic variations that are invisible to less precise instruments, providing valuable insights into natural processes and technological systems.
