In contrast to other gases, oxygen is highly paramagnetic. This physical property is used to
determine oxygen concentration in gases.
Oxygen molecules in an inhomogeneous magnetic field always move toward the higher field
strength. This results in a higher oxygen concentration where the field strength is higher (higher
