The article Ferromagnetic material properties is intended to contain a glossary of terms used to describe (mainly quantitatively) ferromagnetic materials, and magnetic cores.
To describe a soft ferromagnetic material for technical use, the following parameters are specified: (these "effective" above are sizes of a toroid core made from the same material which has the same magnetic properties as the core); These parameters used e.g. in Philips' handbook [2] and Magnetic Materials Producers Association "Soft Ferrites, A Users Guide".
