Gerjesztését

Gerjesztését is a Hungarian term that translates to "excitation" or "stimulation" in English. It refers to the process of raising an object, system, or entity from a lower energy state to a higher one. This can occur in various scientific and technical contexts.

In physics, gerjesztését commonly describes the excitation of an atom or molecule. When an electron within an atom absorbs energy, it can jump to a higher energy level, moving away from the nucleus. This excited state is unstable, and the electron will eventually return to its ground state, releasing the absorbed energy, often as light. This phenomenon is fundamental to understanding spectroscopy and the behavior of light.

In electrical engineering, gerjesztését relates to the process of creating a magnetic field. For instance, in an electric motor or generator, a current flowing through a coil (the exciter coil) produces a magnetic field that is essential for the device's operation. This excitation is what enables the conversion between electrical and mechanical energy.

The term can also be applied more broadly to describe the stimulation or arousal of any system. This might include the gerjesztését of a population, referring to their mobilization or awakening to a particular cause or activity, or the gerjesztését of a biological organism, indicating its stimulation to perform a specific function. The core concept remains the transition from a quiescent or baseline state to one of heightened activity or energy.
