在高中物理《静电场》章节中,电偏转问题是非常常见的问题,而在《磁场》章节中磁偏转问题也是经常遇到.这两种偏转问题有何相同和不同呢?一、问题引入一带正电q,质量为m的粒子初速度大小为v0,分别以如图所示垂直于场的方向分别进入宽度都为L的匀强电场和匀强磁场,并从右边界飞出,电场强度大小为E,磁感应强度大小为B.(粒子重力不计)二、实例分析例1(电视机磁偏转问题)如图2所示,是电视显像管工
In high-school physics “electrostatic field” section, the electrical deflection problem is a very common problem, and in the “magnetic field” chapter is also often encountered in magnetic deflection.While the two deflection problems are the same and different? First, the introduction of the problem A positive q, the mass of the initial velocity of particle size m v0, respectively, as shown in the direction perpendicular to the field into the uniform width L are uniform electric field and uniform magnetic field, and the right out of the field, the electric field Strength of the size of E, the size of the magnetic flux density B. (particle gravity not counting) Second, the case analysis Example 1 (TV magnetic deflection problem) shown in Figure 2, is the video tube workers
