一个电磁力密度的表达式，这是一致的发展归因于爱因斯坦和劳布似乎能够描述光学力的实验做了日期与均匀化介质。然而，一个持续了大约世纪的主要问题涉及到与磁化介质中洛伦兹力描述的通常解释的明显差异。具体地说，爱因斯坦和劳布力密度似乎只包含了与电流密度有关的自由空间磁导率。结果表明，在静态极限下，Einstein力密度和Laub力密度与Lorentz图是一致的。这解决了建立电磁波与物质相互作用的统一力密度描述的关键障碍。
An electromagnetic force density expression that is consistent with a development attributed to Einstein and Laub appears to be able to describe optical force experiments done to date with homogenized media. However, a major question that has persisted for about one century relates to the apparent discrepancy with the usual interpretation of the force description due to Lorentz in magnetized media. Specifically, it had appeared that the Einstein and Laub force density incorporated only the free-space permeability in relation to the force on the electric current density. It is shown here that the Einstein and Laub force density is consistent with the Lorentz picture in the static limit. This resolves a key impediment in establishing a unified force density description for electromagnetic waves interacting with matter.
