Conservation theorems for a moving charge are discussed; in particular we focus attention on an application of Poynting's theorem concerning the interaction of an electric field with a finite size moving charge. Forces and power are expressed solely in terms of fields. In addition an analogous ...
Electric Field Strength1 Electric charges and currents are sources of electric and magnetic fields, and Maxwell's equations [1] provide the mathematical relationships between electro- magnetic (EM) fields and sources. The electric field at a point in space is... D. Hill,M Kanda 被引量: 3发...
The appearance of the time derivative of the acceleration in the equation of motion (EOM) of an electric charge is studied. It is shown that when an electric charge is accelerated, a stress force exists in the curved electric field of the accelerated charge, and in the case of a constant...

In spite of the importance of the previously mentioned contexts, there are not many rigorous results on the motion of charges in concrete magnetic fields. Of course, trajectories can be obtained explicitly in the special case of a uniform field [14], but this situation is rather exceptional. ...
Let us now consider the motion of particles with charge e and mass μ in an arbitrary electromagnetic field. Let the electric field strength be , and the magnetic field strength be . These can be expressed in terms of the scalar potential V and the vector potential A : 56.1 $$E = - ...
All atoms have moving electric charges. Then, why aren't all materials magnetic? What is an electric motor? State its principle. In which process there is the transfer of thermal energy through direct contact of particles? Explain how an electroscope can be charged by the ...
of a conductor carrying current in a magnetic field, and proposes a space charge theory to explain this phenomenon. His theory is based upon the assumption that by the combined effects of collisions and the magnetic field, the electrons in the arc-stream are made to travel in the ...
(1) please determine the charge of the particle and find out its ratio of q/m; (2) if the direction of the magnetic field and the space range is changeless, and the size of the magnetic induction intensity into B , the particle is still from A into the magnetic field with the same...
