Sifat Optis Aktif Air dalam Medan Magnet pada Frekuensi Resonansi 50Hz-60Hz
Abstract: The interaction
between external magnetic field modulated at 50-60 Hz and the dipoles of the
sample induced by laser light modulated at 50-100 Hz has been studied. The
magnetic field has the maximum value of 170 mT produced by a coil of 810 in
turns. The source of light of 632,8 nm and 532 nm is modulated at the resonance
value between 30 Hz and 100 Hz. The optical characteristic behavior studied in
this research is the change of polarization E-direction of laser light in the
aquades samples against the influence of external magnetic field. The result of
experiment indicates that the change of laser polarization angle is linearly
proportional with the increaseasing of modulated frequency and external
magnetic field in sample materials. It is shown that the change of glycerine
concentration changes also linearly direction of polarization. The verdet
constants measured in the experiment for 632 nm and for 532 nm equal to (0,026
± 0,005) V (min/g-cm) and (0,025 ± 0,003) V (min/g-cm), respectively.
