一、磁场、重力场混合场 带电体为液滴、带电小球等重力不可忽略时,带电粒子进入磁场,将在洛伦兹力和重力共同作用下运动. 1.无约束情况:当粒子垂直磁场方向进入时,重力和洛伦兹力若构成一对平衡力,带电体将做匀速直线运动;若重力和磁场力不能构成 First, the magnetic field, the gravity field mixed field charged body for the droplet, the charged ball, etc. When the gravity can not be ignored, the charged particle enters the magnetic field and will move under the action of the Lorentz force and gravity. 1. Unconstrained situation: When the particle is vertical When the direction of the magnetic field enters, if gravity and Lorentz force form a pair of balancing forces, the charged body will perform a uniform linear motion; if gravity and magnetic field forces cannot constitute
