MAGNETIC FIELD MEASURING METHOD AND MAGNETIC FIELD MEASURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a measuring method capable of precisely measuring a wide-ranging low magnetic field absolute strength, and a measuring apparatus capable of performing the method by using a single probe. SOLUTION: This magnetic field measuring method includes a process that detects a change in a magnetic flux parallel to the static magnetic field generated by magnetic resonance. This magnetic field measuring apparatus is provided with at least a paramagnetic species, a means that irradiates the paramagnetic species with an electromagnetic wave, and a detection means that detects the change of the magnetic flux directed in parallel to the static magnetic field.
