Rubidium magnetometer

A Rubidium magnetometer is a device that measures magnetic fields using atoms of rubidium gas. When exposed to a magnetic field, the electrons in rubidium atoms react by changing their energy states. By shining a laser through the gas and detecting how it affects the atoms, the device can determine the strength and direction of the magnetic field with high precision. This technology is used in applications like geophysical surveys, detecting underground resources, and in navigation systems, providing accurate magnetic measurements without requiring large, complicated equipment.
