物理学是一门崇尚理性、重视逻辑推理的科学,其命题必须遵循事实。电磁感应在高中物理中占有非常重要的地位,其中导体棒切割磁感应线类问题更为常见,在该类问题中除涉及楞次定律、法拉第电磁感应定律等电磁感应本身内容外,还常与电路、动力学、能量等知识进行综合考查,在历年高考中屡屡出现。因此,在平时的备考训练中也经常命制这类问题。本文推导出了常见导体棒切割磁感线运动的一般规律,明确了在此过程中几个物理量间必须满足的关系,
Physics is a science that advocates rationality and values logical reasoning. Its proposition must follow facts. Electromagnetic induction in high school physics occupies a very important position, in which conductor bar cutting magnetic induction line is more common in this type of problem except involving Lenz’s law, Faraday’s law of electromagnetic induction and other electromagnetic induction itself, but also often with the circuit , Kinetics, energy and other knowledge to conduct a comprehensive examination of the college entrance examination in the calendar year after year often appear. Therefore, in peacetime pro forma training is often the life of such issues. This article deduces the common law of common magnetic rod cutting magnetic induction line movement, defines the relationship between several physical quantities that must be satisfied in this process,
