A positive Verdet constant corresponds to L-rotation ( anticlockwise ) when the direction of propagation is parallel to the magnetic field and to R-rotation ( clockwise ) when the direction of propagation is anti-parallel.

The Faraday effect can, however, be observed and measured in a Terbium-doped glass with Verdet constant as low as ( H " " 20 rad T " 1 m " 1 ) ( for 632 nm light ).

The highest Verdet constants are found in terbium doped dense flint glasses or in crystals of TGG . The Faraday effect is chromatic ( i . e . it depends on wavelength ) and therefore the Verdet constant is quite a strong function of wavelength.

Following the laws which govern the Faraday effect, the rotation of the targeted radiation is directly proportional to the strength of the magnetic field, the width of the vapor cell and the Verdet constant ( which is dependent on the temperature of the cell, wavelength of the light and sometimes intensity of the field ) of the vapor in the cell.
