A time-varying electric current produces electromagnetic waves, which are used in telecommunications to broadcast data. AC vs DC Current Based on the flow of charge, the electric current is classified into two types, i.e., alternating current (AC) and direct current (DC). AC Current The flow...

An electric motor makes use of this electromagnet to generate a magnetic field that is ultimately used to generate mechanical energy from electrical input. Hence, the answers are option (A) and (C).NoteA current carrying wire tends to create a magnetic field around it. This...
The magnetic effect of electric convectionXXXXXXXXX
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 fluctuations of electric current quantified by the susceptibility. We find that our results are in ...
The goal is to explain qualitatively the mechanism for the steplike nature ofthe acoustoelectric current as a function of gate voltage and the oscillations when a magnetic fieldis applied. A transfer Hamiltonian formalism is employed.PACS numbers:1. INTRODUCTIONIn recent experiments, it has been ...
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....
Cosmic magnetic structures have in common that they are anchored in a dynamo, that an external driver converts kinetic energy into internal magnetic energy, that this magnetic energy is transported as Poynting flux across the magnetically dominated structure, and that the magnetic energy is released ...
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...
