I describe an elementary way of introducing electromagnetic field momentum. By considering a system of a long solenoid and line charge, the dependence of the field momentum on the electric and magnetic fields can be deduced. I obtain the electromagnetic angular momentum for a point charge and magnetic monopole pair partially through dimensional analysis and without using vector calculus identit...

Theoretical and experimental evidences support the hypothesis that extremely low-frequency electromagnetic fields can affect voltage-gated channels. Little is known, however, about their effect on potassium channels. Kv1.3, a member of the voltage-gated potassium channels family originally discovered in the brain, is a key player in important biological processes including antigen-dependent act...

Can the wavelength of a classical electromagnetic field be arbitrarily small, or its electric field strength be arbitrarily large? If we require that the radiationreaction force on a charged particle in response to an applied field be smaller than the Lorentz force we find limits on the classical electromagnetic field that herald the need for a better theory, i.e., one in better accord with exp...

An electromagnetic field of simple algebraic structure is simply derived. It turns out to be the G = 0 limit of the charged rotating Kerr-Newman metrics. These all have gyromagnetic ratio 2, the same as the Dirac electron. The charge and current distributions giving this high gyromagnetic ratio have charges of both signs rotating at close to the velocity of light. It is conjectured that somethi...

Based on the Maxwellian quaternionic electromagnetic theory, the electromagnetic interaction, the gravitational interaction and their coupling influence with the dark matter field in the octonionic space are discussed. The research results reveal the close relationships of dark matter field with electromagnetic field and gravitational field. In the electromagnetic field, the variation of field ...

To quantize a classical system means that we pass from a classical description of the system to the quantum description. The classical description involves a classical Lagrangian or Hamiltonian, and a set of classical coordinates describing the dynamical state, that is, a set of q’s and q̇’s or q’s and p’s. Classical observables are functions of these coordinates. In the quantum description, the...

in Gaussian units, where is the electric charge density, A is the magnetic vector potential (where ∇ ·A = 0 for static fields in both the Coulomb and Lorenz gauges), E is the electric field, B is the magnetic field, V is the electric scalar potential, and J is the electric current density. The first form is due to Faraday and Maxwell, the second form is due to Poynting Thomson and Poincaré, the...

Abstract. We obtain explicit analytical expressions for the quadrature variances and the photon distribution functions of the electromagnetic field modes excited from vacuum or thermal states due to the non-stationary Casimir effect in an ideal one-dimensional Fabry–Perot cavity with vibrating walls, provided the frequency of vibrations is close to a multiple frequency of the fundamental unpert...

We discuss a model for the integer quantum Hall effect which is based on a Schroedinger-Chern-Simons-action functional for a non-interacting system of electrons in an electromagnetic field on a mutiply connected manifold. In this model the integer values of the Hall conductivity arises in view of the quanti-zation of the Chern-Simons-action functional for electromagnetic potential.
