摘要
磁场的本质是运动电荷所产生的附加电场效应,磁场中的洛伦兹力是运动电荷所受电场力的分项。与一般教材所采用的电磁张量变换不同,通过研究运动电荷位置矢量的洛伦兹变换关系,研究电荷间库仑力的变换形式,从基础物理的角度解释磁场的电场本源,通过对磁力本质的探讨,厘清电学与磁学的相互关联,同时也验证了相对论洛伦兹变换的正确性。
The essence of the magnetic field is the additional electric field effect that produced by the moving electric charge. The Lorentz force in the magnetic field is one item of the force of the moving electric charge. Dissimilarities as the e- lectromagnetism tensor transformation that general teaching material adopted, with the research of position vector transformation relation of moving electric charge, study the transformation form of Coulomb force of electric charge, explain the electric field origin of the magnetic field from an eye of foundational physics. By the hypostatic study of magnetic force, it clarifies the mutually connection between electricity and magnetics, and also verifies the accuracy of the relativity transformation.
