摘 要 針對目前高校開設(shè)的磁致旋光效應(yīng)實驗中存在的不足，將相關(guān)實驗公式進一步推導(dǎo)，得到同種旋光玻璃的費爾德常數(shù)和入射光波波長的數(shù)學(xué)關(guān)系，并將其擴充到實驗中，使得該實驗項目在內(nèi)容設(shè)計上更加飽滿、嚴謹和完善。
關(guān)鍵詞 磁致旋光效應(yīng)；實驗；費爾德常數(shù)

Improvement of Experiment of Magneto-Optical Rotation Effect
FAN Shuyuan1， WU Liang2， LI Dongdong1
Abstract In view of the shortcomings in the experimental project of magneto-optical rotation effect in universities， their relevant theories are further deduced to obtain the mathematical relationship between Verdet constant and incident light wavelength of the same kind of optical rotation glass. The corresponding content can be extended to the experi-ment， which not only makes the experimental project more full， rigorous and perfect， but also further promotes students’ thinking.
Key words magneto-optical rotation effect; experi-ment; verdet constant

法拉第在探索電、磁、光之間的聯(lián)系時，發(fā)現(xiàn)當(dāng)一束線偏振光穿過具有固有磁矩的介質(zhì)時，如果在光的傳播方向上加上磁場，那么出射光的偏振面將轉(zhuǎn)過一個角θ，這種現(xiàn)象被稱為法拉第效應(yīng)或磁致旋光效應(yīng)[1-2]。（剩余1935字）
