论文部分内容阅读
《磁场》内容可以分成三部分,即:基本概念、安培力;洛伦兹力、带电粒子在磁场中的运动;带电粒子在复合场中的运动.其中磁感应强度、磁通量是电磁学的基本概念,应认真理解;载流导体在磁场中的平衡、加速运动,带电粒子在洛伦兹力作用下的圆周运动等内容应熟练掌握;常见磁体周围磁感线的空间分布观念的建立,常是解决有关问题的关键,应注
The content of “Magnetic Field” can be divided into three parts, namely: basic concepts, Ampere force; Lorentz force, motion of charged particles in a magnetic field; motion of charged particles in a complex field. Magnetic induction and magnetic flux are basic concepts of electromagnetism. Should be carefully understood; the balance of current-carrying conductors in the magnetic field, accelerated movement, the circular motion of charged particles under Lorentz force should be mastered; the establishment of the concept of spatial distribution of magnetic induction lines around common magnets is often The key to solving the relevant issues should be
