一、考试概况电场部分考查重点在电势、电功、电势能、电场强度等基本知识;粒子加速、偏转,电容、平行板电容器的电容也是考查的热点。磁场部分主要考查了带电粒子在磁场中的运动(洛仑兹力)、安培力及安培力矩、典型磁场的描述(主要在电磁感应部分考查)。本部分命题的特点是: (1)基础全面,重点突出:重点在电场强度、电势、电势差、电容等基本概念;在匀强电场或匀强磁场中,电荷的加速、偏转;以及运用功能关系、能量转化这些以力学为基础的基本规律上。 (2)在涉及磁场力的考题中,常包含有重力、电场
First, the test profile Electric field part of the examination focused on the potential, electrical power, potential energy, electric field strength and other basic knowledge; particle acceleration, deflection, capacitance, parallel plate capacitor capacitance is also a hot spot. The magnetic field part mainly examines the motion of charged particles in the magnetic field (Lorentz force), Ampere force and Ampere torque, description of a typical magnetic field (mainly examined in the electromagnetic induction part). The characteristics of this part of the proposition are: (1) Basic comprehensive and focused: Focus on the basic concepts of electric field strength, potential, potential difference, capacitance, etc.; acceleration and deflection of charge in a uniform electric field or uniform magnetic field; and use of functional relationships , energy conversion these basic laws based on mechanics. (2) Gravity and electric fields are often included in questions involving magnetic force.
