安培力的本质

The Essence of Ampere Force

安培力是载流导线在磁场中所受的力,一般认为安培力的微观本质是载流导线中自由电子所受到的洛仑兹力,是洛仑兹力的宏观表现。本文提出安培力的本质是电场力,是外加磁场在导体中诱导出的附加电场的电场力。

Ampere force is the force of current-carrying wires in magnetic field.It is generally believed that the microscopic nature of Ampere force is Lorentz force of free electron in the current-carrying wire,which is the macroscopic manifestation of Lorentz force.The essence of Ampere force is electric field force,which is electric field force induced by external magnetic field in conductor.This article has carried on the detailed demonstration to this.
