Vector potential coil and transformer
2015 IEEE Magnetics Conference (INTERMAG), 2015For quantum systems, vector potential plays a very important role [1] but, for classical macroscopic systems, it does not seem to play a very significant role. In this study, we demonstrate a vector-potential coil and a vector-potential transformer that each use a long flexible solenoid wound around a hollow cylinder. These devices generate a curl-free

Maxwell and the Vector Potential
Isis, 1967HE LITERATURE OF PHYSICS today resounds with a common attitude toward the potentials in electromagnetic theory, an attitude presented in several different forms. Sometimes we find an ontological statement that the electric and magnetic fields are real quantities but the potentials are mathematical fictions introduced only for convenience in solving the

Electrical Engineering, 1936
In this paper an attempt is made to describe the general properties of the magnetic vector potential, to make clear its relation to the fundamental equations of electromagnetic theory, and to describe its use in the derivation of general relationships for electric circuit analysis.

Determination of a vector potential
Radio Science, 1984A vector potential is determined for a static field attributable to sources induced on a perfectly conducting surface B. With the electrostatic problem it is shown that for closed and open surfaces existing methods for the construction of the potential are inconvenient and inadequate respectively, and alternative solutions are developed in both cases.

On the photon vector potential
Chemical Physics, 2001Abstract A method of calculating the expression for the single-photon classic vector potential is proposed. The calculation is performed within the model framework of a non-relativistic one-dimensional harmonic oscillator interacting with a quantized electromagnetic field and with the field of a single external photon. The calculated vector potential

Toroidal vector-potential transformer
2017 Eleventh International Conference on Sensing Technology (ICST), 2017We investigated the characteristics of a triple coil comprising a very long, thin, flexible solenoid coil wound around a hollow toroid. In ordinal magnetic-toroidal coils, the current flows in the poloidal direction, generating magnetic field in toroidal direction, but in our vector-potential coil, the magnetic flux flows in the poloidal direction ...

An introduction to the vector potential
European Journal of Physics, 2004The authors discuss the physical means of the vector potential \(A\) in electromagnetism. They consider a long solenoid and the magnetic induction field \(B\) within and without the solenoid and point out that, in the absence of electric charge that the electric field generated at any point is given by \(E= -{\partial A\over\partial t}\).

Vector potential photoelectron microscopy
Review of Scientific Instruments, 2011A new class of electron microscope has been developed for the chemical microanalysis of a wide range of real world samples using photoelectron spectroscopy. Highly structured, three-dimensional samples, such as fiber mats and fracture surfaces can be imaged, as well as insulators and magnetic materials.

The vector potential revisited
Electrical Engineering in Japan, 1993AbstractThe vector potential in electrodynamics is investigated through the decomposition of its form to the following two parts: 1) the so‐called transverse part represented by a divergenceless vector; and 2) the longitudinal part represented by an irrotational vector.
