用双通道偏振计对大麦哲伦星云中的30颗恒星进行了星际偏振观测。最大偏振度为0.068等，整个星云的P/A最大值为0.07。平均值P/Avderived为0.05，这表明云几乎是正面看的。电矢量的排列似乎在千秒差距量级的大距离上是均匀的，由电矢量指示的磁场的平均方向似乎与云的结构有关。
Observations of interstellar polarization have been made for thirty individual stars in the Large Magellanic Cloud, with a double-channel polarimeter. The maximum polarization found is 0.068 mag and the maximum value ofP/Avobtained for the whole Cloud is 0.07. The average valueP/Avderived is 0.05 and this can be taken to indicate that the Cloud is seen nearly face on. The alignment of the electric vectors seems to be uniform over large distances of the order of kiloparsecs and the mean direction of the magnetic field indicated by the electric vectors seems to be related to the structure of the Cloud.
