电磁材料中的自感电荷电流及其在扭秤实验中的影响
On the self-induced charge currents in electromagnetic materials and its effects in the torsion balance experiment
摘要：
本文研究了电磁材料中的自感电荷流及其效应。简要讨论了异向介质自感电荷流对光子有效静止质量的贡献。我们主要集中在扭矩，这是由自感电荷流在稀等离子体与星际磁场的相互作用，作用在扭秤的扭秤实验。计算结果表明，次级宇宙射线中的μ子和α粒子对光子的有效静止质量约为10^{-54} Kg，这与Luo的旋转扭秤实验中新得到的光子静止质量上限相比较。
英文摘要：
We concern ourselves with the self-induced charge currents in electromagnetic materials and some related topics on its effects in the present paper. The contribution of self-induced charge currents of metamaterial media to photon effective rest mass is briefly discussed. We concentrate primarily on the torque, which is caused by the interaction of self-induced charge currents in dilute plasma with interstellar magnetic fields, acting on the torsion balance in the torsion balance experiment. It is shown by our evaluation that the muons and alpha-particles in secondary cosmic rays will contribute an effective rest mass about 10^{-54} Kg to the photon, which is compared to the newly obtained upper limit on photon rest mass in Luo's rotating torsion balance experiment.
