Magnetisierungsinduktivität

Magnetisierungsinduktivität, often translated as magnetizing inductance or magnetization inductance, is a fundamental property of magnetic components, particularly inductors and transformers. It represents the inductance that would exist if the magnetic core were absent, meaning it is solely due to the coil's geometry and winding. More precisely, it characterizes the inductive behavior of the magnetic circuit when it is not saturated. This means it describes how effectively the coil stores magnetic energy in the core when operating below its saturation point.

The value of magnetisierungsinduktivität is influenced by factors such as the number of turns in the coil, the material properties of the magnetic core (specifically its permeability), and the geometry of the core and coil. A higher permeability core will generally result in a higher magnetisierungsinduktivität for a given coil. It is a crucial parameter for understanding the low-frequency behavior of inductive devices and is particularly relevant in applications where the magnetic circuit might not reach saturation, such as in some types of filters or in the open-circuit secondary of a transformer. It is distinct from leakage inductance, which relates to the magnetic flux that does not link both windings in a transformer.
