PENGARUH MEDAN MAGNET TERHADAP SUDUT POLARISASI SINAR LASER PADA AIR DAN LARUTAN NaCl (Influence of Magnetic Field Toward Polarization Angle Of Laser Ray To Water And NaCl Solution)

Abstract

Had been done experiment about influence of external magnetic field toward polarization angle of laser ray to NaCl various concentration 5%,10%,15%,20%,25%,30%,35% and water. Optical characteristic behaviors studied in this research were vibration direction rotation of electric fields b from transmitted laser trace because of external magnetic fields in the transparent materials. The result of experiment indicated increasing polarization angle of laser ray proportional with magnetic field touched to transparent material. If the magnetic fields touched to the transparent materials were higher, then the polarization angle change of laser ray also experienced increase linear. For NaCl solution concentration variation, it was found that the change in polarization direction was directly comparable to its concentration. In addition, from experiment, it was also found that Verdet’s Constant water is (0,03±0,002)min/Gcm and NaCl 0,125 molal is (0,16±0,015)min/G-cm.
