Faraday effect (rotation)
A magnetic field rotates the polarization of light proportionally to magnetic field strength.
Surface Magneto-Optic Kerr Effect (SMOKE)
Light reflected from a magnetized surface (object) can change in polarization and intensity.
Zeeman effect spectroscopy
A magnetic field splits spectral lines in a manner that is dependent on the strength of the magnetic field.
Measurement of the magnetic field of the Sun and other stars, the Earth and plasmas.
Magnetographs based on light analysis.
Laser/LIDAR Magnetometry (Laser Guide Star tech - LGS) Larmor precession frequency interrogation
Magnetic field strength is proportional to Larmor frequency (precession frequency). By measuring the Larmor frequency of atoms, we can determine the magnetic field in which the atoms are immersed.

Magnetic Resonance - Magnetic Resonance Imaging (MRI)
Magnetic Resonance: A magnetic field splits spin energetic levels and induces spin precession. Energy transitions under conditions of Magnetic Resonance.
MRI: Polarization
A magnetic field induces spin polarization and a net magnetization
MRI: Detection
An RF tips the magnetization with energy absorption. During magnetization decay a signal (FID) is emitted.
MRI: Polarization enhancement techniques
MRI: Detection RF pulse design
