Proton magnetometer

A proton magnetometer is a type of magnetic sensor that measures the Earth's magnetic field by detecting the precession frequency of protons in a sample, typically in a fluid like water or a hydrocarbon. This instrument operates based on the principles of nuclear magnetic resonance (NMR). ### Key Features: 1. **Operating Principle**: Proton magnetometers utilize the magnetic properties of protons found in hydrogen atoms. When placed in a magnetic field, these protons align with the field.
