A charged particle is moving in a uniform magnetic field. The magnetic field strength is 3 T and the charge of the particle is 2 C. If the particle moves in a circular path of radius 2 m with a speed of 3 m/s, what is the magnetic force? A. 9 N B. 12 N C. 18 N D. 24...
The theory of the motion of a charged particle in a magnetic field presents several difficult and unintuitive features. The derivation of the quantum theory does not require the classical theory; nevertheless it is useful to first review the classical theory in order to show that some of these ...

*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...
Geladene Teilchen im Magnetfeld: In this demonstration particles are entering the region of the magnetic field with their velocities being perpendicular to the magnetic field lines. In such a situation the magnetic force serves to move the particles in a circular path. According to the "right ha...
Which of the following explains why a magnetic field does no work on a moving charged particle?( ) A.The magnetic force is conservative. B.The magnetic force depends on the speed of the particle. C.The magnetic force is always perpendicular to the direction of motion. D.There is always...
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 ...
Thermal relaxation and entropy for charged particles in a heat bath with fields It is demonstrated with full rigor that relaxation to thermal equilibrium of a very dilute species of charged particle in a heat bath of other particles must always occur, even in the presence of a magnetic field....
