An electric bulb uses the principle of heat generation in the filament due to electricity, and hence no magnetic effect is used. A geyser also uses the heat effect as the heating rod increases in temperature and causes the water surrounding it to boil slowly. The effect of...
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 samples of the alloy have the form of narrow strips with different lengths. It is found that the magnetoelastic parameters of the dc-treated alloys depend on the magnetic field in a qualitatively different way. From the behavior of the magnetic and magnetoelastic parameters of the alloys ...
This skin effect of electric current will lead to the phenomenon that the Joule heat on the surface of the material is higher than that at the center of the material [44]. Skin thickness δ can be calculated by the following formula: [Math Processing Error]δ=ρeπμf, (2) where ρ...

This non-zero susceptibility difference acts as a background to the Chiral Magnetic Effect, i.e. the generation of electric current along the direction of magnetic field in the presence of topological charge. We propose a description of the Chiral Magnetic Effect that takes into account the ...
