Based on the results of the distribution of questionnaires to students and interviews with physics teachers, there are two things that the author found. The first is students still have difficulty in determining the direction of Lorentz force and the seco... see more

In this paper, we study the effects of the Lorentz force and the induced anisotropic thermal conductivity due to a magnetic field on the flow and the heat transfer of a ferro-nanofluid. The ferro-nanofluid is modeled as a single-phase fluid, where the vis... see more

The radiation self-force of a point charge is obtained in a mathematically exact way in the framework of Distribution theory: the world line and the electromagnetic field of a point charge are treated as Distributions; the energy-momentum tensor of the po... see more

Is there a point of divergence between Classical Mechanics and Electromagnetism? This discrepancy is raised by many authors and arises between Newton's third law and the equation of Lorentz forces. Due to the transcendence of these expressions, their wide... see more

We analyzed null magnetic trajectories of a magnetic field on a timelike surface in Minkowski 3-space. We show that the Lorentz force can be written into the Darboux frame field of a null trajectory on the surface. We give the necessary and sufficient con... see more

 The value for the Lorentz contraction to produce a discrepancy for a hypothetical number that reflects a property (21.34) of sub-matter space was calculated. When applied to time the contraction would be ~35 min. The difference in mass-equivalent en... see more

The 0.3-mm-thick, 50-mm-wide and 100-mm-long YBa2Cu3O7-x superconducting bridges with a laser-written, single, ?-shaped channel have been investigated by means of electronic transport measurements at temperatures below the onset of the bridge's supercond... see more

In this paper, the modeling of a steady state two phase flow heated through a vertical upward flow under electro-magneto-hydro-dynamic forces is presented. The thermal non-equilibrium, non-homogeneous, two-phase flow model consisting of mass, momentum and... see more

While mechanics was developed under the idea of reciprocal action (interactions), electromagnetism, as we know it today, takes a form more akin to unilateral action. Interactions call for spatial relations, unilateral action calls for space, just one refe... see more
