摘要
本文对洛伦兹力和安培力的关系以及动生电动势产生机理进行了再探讨,认为安培力是载流导线中所有电荷所受的洛伦兹力的总和;从动生电动势的产生过程进一步讨论了洛伦兹力的做功问题,洛伦兹力所做的总功为零,但其分力可以做功。洛伦兹力的分力提供了产生动生电动势的非静电力。
The relations between Lorentz force and amepere force and the formation mechanism of motional electromotive force was studied further. It is considered that amepere force is the sum of Lorentz forces acted on all electric charges in the wire. The problem of doing work of Lorentz force was discussed further through the course of producing motional electromotive force. The total works of the Lorentz force are zero, but the work of its component force is not zero. The component of Lorentz force provides the non-electrostatic force for producing motional electromotive force.
