Hanle effect
Definición
- The polarization arising from line scattering in the presence of "weak" magnetic fields. The effect occurs when precession around magnetic field depolarizes and rotates polarization of the scattered light. The Hanle effect is sensitive to ~10³times smaller field strengths than the Zeeman effect. It is in particular used to measure the weak magnetic field of the solar prominences, which is 10⁻³ tesla and over 10⁻² tesla for the active prominences.
