标题： Fundamental longitudinal electromagnetic (EM) force investigation using DC current

摘要： 本文工作的目的是调查历史上关于存在一种纵向电磁（EM）力分量作用于金属原子电流元件的主张，这种力的方向与其内部流过的电流平行。 这超出了传统教科书物理学预测的范围，但其存在已先前被暗示，并且如果最终得到证实，将对物理学理论以及许多技术应用产生重大影响，特别是那些涉及高电流密度（> 10^9 A/m²）的应用。 这里描述的实验基于测量浸没在一个含有液态金属的槽中的铜装甲所受的力，通过该槽的直流电是恒定的。 实验的同轴对称性（CRE 同轴反冲实验）能够将中心装甲上的所有净力限制在与其中流过的电流平行的方向上。 所有实验数据都与电路中流过的电流相关联，对装甲所受的力进行了测量。 对装甲沿中心轴的长度和位置进行了变化，并对液态金属配置进行了修改。 提供了原始和处理后的结果，并描述了一种实验技术，揭示了轴向机械接触力和纵向电磁力之间存在强证据。 最初由安培在1822年提出的电磁力定律包括一个纵向分量，并已被发现与迄今为止的所有实验一致，包括这些报告的发现，被认为是候选解释理论。 显示英文摘要

摘要： The purpose of this work was to investigate historical claims of the existence of a longitudinal ElectroMagnetic (EM) force component acting on metallic atomic current elements in a direction parallel to the current flowing through them. This lies outside conventional textbook physics predictions, yet its existence has been indicated previously and if eventually confirmed will have a significant effect on physics theory and many technological applications, especially those involving high current density (> 10^9 A/m2). The experiment described here is based on the measurement of force on a copper armature submerged in a trough containing liquid metal through which constant DC current is passing. The coaxial symmetry of the experiment (CRE Coaxial Recoil Experiment) was able to limit all net force on the centred armature to the direction of interest, parallel to the current within it. All the experimental data related the measured forces on the armature to the current flowing through the circuit. Variations were made to the length and location of the armature along the central axis as well as modifications to the liquid metal configuration. Raw and processed results are presented, and an experimental technique described that revealed strong evidence for the existence of and discrimination between axial mechanical contact forces and longitudinal EM force. The original EM force law, proposed in 1822 by Ampere, includes a longitudinal component and has been found to be qualitatively consistent with all experiments to date, including these reported findings, and is considered a candidate explanatory theory.
