Abstract
The paper reviews major topics which concern the design of most common choke types from the point of view of materials research. Measurements of permeability (μ) frequency- and field-dependence as well as measurements on model chokes prove advantageous properties of metallic glasses. Preference of rotational processes in core magnetization is pointed out. Limitations in the use of high μ, of higher induction and in the feasibility of core-dimensions reduction are analysed too
