“…It has been demonstrated that it is consistent with Maxwell's equations [54][55][56][57][58]. Research into Weberian electrodynamics has received a significant contribution from Assis [38,55,[59][60][61] and has been applied to several pure and applied problems [43,52,57,[62][63][64][65][66][67][68][69][70][71].…”

Unipolar induction has been a heavily discussed phenomenon in the realm of electrodynamics, with research and experiments proposing and supporting different ways to explain the observed effects. This paper presents a novel model to predict induced electromotive forces in a Faraday generator, based on direct interaction between conductor charges. It is compared with predictions that are usually obtained through considerations of Lorentz force, flux linking or flux cutting rules. A standard apparatus provides additional experimental measurements that show good agreement with the theory.

“…However, this manifestation of the Meissner effect has kindled a lasting controversy [2,3] over the very nature of this force, because H remains unaltered at T c . In particular, quantum [4] and classical [5][6][7] origins have been called forward. Nevertheless, this debate has remained so far inconclusive, because the original experimental setup [8] does not enable one to sort out the relevant interpretation.…”

The properties of the current-induced Hall effect are analysed, for which the static magnetic field, supplied by an external source in the traditional experiment, is created by the current itself. The special experimental setup, needed for its observation, is described. It is shown how, combined with the skin effect, it could give access to the concentration of conduction electrons in superconductors. Besides this experiment might permit to dodge shortcomings, ensueing from the Meissner effect and limiting severely the sensitivity of the conventional Hall voltage measurement.

“…Third, the software package CPO [34] is used to calculate beam deflections, which employs the BEM to obtain numerical solutions. Recently, research interest in Weber electrodynamics has increased, where Weber's force has not only been applied to electron beam deflection [35][36][37], but also to other electromagnetic phenomena, such as induction [38][39][40], and superconductivity [41,42]. Moreover, the theory has further been connected to the fine structure of the hydrogen atom [43,44] and even Planck's constant [45,46].…”

To aid with the design, evaluation, and optimisation of charged particle instrumentation, computer modelling is often used. It is therefore of interest to obtain accurate predictions for trajectories of charged species with the help of simulation. Particularly for solenoids and coils, which are often used for guiding, deflecting or focussing particle beams, knowledge of the magnetic field is required, especially in the fringing field regions. A novel model, which is based on a direct-line-of-action force between interacting charges, is described in this paper which accurately predicts the deflection of an electron beam trajectory traversing through a coil and the fringe field region. The model is further compared with a standard field model and a commercially available software package. Additionally, a relatively straightforward experiment has been designed and implemented to verify the simulation results, where it is found that the presented direct-action model is equally as accurate as field-based simulations compared with the experimental results. Furthermore, the magnetic field of a solenoid is visualised and analysed in terms of its radial, axial, and total field strength and compared to a force map obtained from the direct-interaction model. This representation allows for further comparison of the field and force interaction models and it is found that they are qualitatively the same.
