Magnetic core - Wikipedia
网页A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, generators, inductors, loudspeakers, magnetic recording heads, and magnetic assemblies.
Magnetics - Inductor Core Material and Shape Choices
网页Among powder cores, MPP material is superior for core loss properties, and has highest available permeability. High Flux has an advantage when space and DC bias performance are critical constraints. Kool Mμ is consistently a lower cost option than MPP or High Flux, and is offered standard in both toroids and E-core geometries.
