Web5 jan. 2010 · The induced current is proportional to the coupling between the two wires. For the most part, the coupling would depend on the spacing between the two wires, the lengths of the two wires, and any shielding, and if the conductors are twisted, etc. So the coupling is basically determined by the physical layout. WebThe charges (electrons) in the conductor are not pushed in motion directly by the change in flux, but by a circular electric field(not pictured) surrounding the total magnetic field of inducing and induced magnetic fields. This total magnetic field induces the electric field. Articles about Electromagnetism Electricity Magnetism History Textbooks

Web24 sep. 2024 · Electric current is defined as the flow of electrons in a circuit. This current is derived from the continuous jumping of the negatively charged electrons from one atom to another.
