He also noticed that the compass only gets deflected when brought into a certain range of the wire. Upon changing the direction of current flow in the wire, he noticed that the compass deflected on the opposite side too. And that is how the magnetic effect of electric cu...

Feasibility in using electric and magnetic fields as a plasma control tool during high-power laser welding is explored in this paper. Preliminary results indicated that both fields can influence the shielding effect of the plasma above the keyhole. It was found that at suitable field parameters the...

We study the effect of finite electric field on the density of states (DOS) in a two-dimensional disordered system, extending our previous work about the magnetic field effect. Two cases are considered: (i) uniform electric field E and (ii) crossing fields E and H. The electric field supp...
MAGNETIC EFFECT OF CURRENT 1. Concept of Magnetic Field If we place or suspend a small magnetic needle near a bar-magnet, the need..
The influence of a strong electric field F on the polarization of light scattered elastically by small gaseous molecules is investigated. Two effects are found: 1. (i) The field distorts the molecules, thereby changing their polarizabilities. If they are isotropically polarizable when F = 0, ...
magnetic field effectpoint defectssingle-crystal NaClpulsed electric fieldIt is established that exposing crystals to a pulsed electric field with an amplitude of 10 3 kV/m creates metastable states of the point defects, while a magnetic field with an induction of 7 T causes them to relax....
This effect of magnetic field confinement turning them into near-field magnets/near-field magnetic can be seen further down in the video „strange magnet with no field“ and in „secrets of fields and magnetism“ between 4.5 and 5.5min. If magnetic currents form short-circuits, they lose ...
