| 摘 要： | 对Melvin磁宇宙中球对称质量外部区域的电磁场能量动量张量进行了研究, 给出电磁场能量的分布规律;然后以均匀磁场中的Schwarzschild黑洞为例, 通过数值计算出球对称引力场对均匀磁场能量分布的影响. 结果表明, 时空的弯曲会使均匀磁场的能量增大.

| Abstract: | Electromagnetic (EM) energy-momentum tensor in external region of spherical symmetric mass in Melvin's magnetic universe is discussed, and distributional disciplinarian of electromagnetic energy is obtained. By numerical calculation for Schwarzschild black hole in a uniform magnetic field, the influence of gravitational field to uniform magnetic field is given. The results suggest that the energy of the uniform magnetic field will be greater in curved space-time than in Minkowski space-time. |
