*11 The diagram shows the track of a charged particle in a magnetic field. The field is at right angles to the plane of the paper and its direction is out of the plane of the paper.AB is a thin sheet of lead that the particle passes through.A PQ B Work out the direction of movem...
The radial spread of charged particles emitted from a point source in a magnetic field is a potential source of systematic error for any experiment where magnetic fields guide charged particles to detectors with finite size. Assuming uniform probability as a function of the phase along the particle...
A. parallel to the magnetic field B. perpendicular to the magnetic field C. at an angle of 45 degrees to the magnetic field D. in any random direction 相关知识点: 试题来源: 解析 B。解析:当带电粒子在磁场中运动时,垂直于磁场方向时受力最大。A 选项平行于磁场时受力为零;C 选项 45 度时...
In the continuum dielectric theory one considers the interactions between the test particle and its polarization cloud. In the presence of a strong magnetic field, there exists no suitable parameter of smallness. Linearized and perturbative treatments are not more valid and must be replaced by ...
Charged Particle in a Magnetic Field • Consider a particle moving in an external magnetic field with its velocity perpendicular to the field • The force is always directed toward the center of the circular path • The magnetic force causes a centripetal acceleration, changing the ...
摘要: If a charged particle of charge e moves in an electromagnetic field, the Lorentz force $$ F = e\left( {E + \frac{v} {c} imes B} ight) $$ (9.1) acts on the particle. The electric and magnetic...DOI: 10.1007/978-3-642-56826-8_9 年份: 2001 ...
Stochastic motion of a charged particle in a magnetic field: II Quantum Brownian treatment We study the quantum Brownian motion of a charged particle in the presence of a magnetic field. From the explicit solution of a quantum Langevin equation w... S Dattagupta,J Singh - 《Pramana》 被引量...
A magnetic force can supply centripetal force and cause a charged particle to move in a circular path of radius r=mvqB.r=mvqB. The period of circular motion for a charged particle moving in a magnetic field perpendicular to the plane of motion is T=2πmqB.T=2πmqB. H...

This chapter discusses magnetic fields restricted to lines of force that are always parallel to one another, whether they are curved or straight. However, a most interesting effect appears when a charged particle in a field is followed where the lines of force converge toward one another. By ...
