 * maximum permeability is not used in Philips handbook - it was took from other source;
 * A_min is A_e min in Philips handbook - probably typo error (it is just below A_e) - need verification;
 * µ_i uses 'lim' in Philips handbook - seems to be 'overkill'; also the definition in handbook is physically incorrect, as it does not take into account the B_r - remaining induction when H=0 - the 'lim' is infinite! 'initially demagnetized' added to the handbook definition;
 * saturation induction, resistivity, and mass density - not specified in the handbook in 'SYMBOLS AND DEFINITIONS OF TERMS', but used in material description; the first is not obvious: it is measured for some standard H values, these values are different for different µ;
 * hysteresis constant and d.c. sensitivity constant - seems the explanation in the handbook is unclear and may contain typo error - need other source for their definitions;
 * 'effective' parameters for 'magnetic core parameters' - comparison to a toroid was for the volume only, seems it is correct for all four parameters;


 * Why doesn't this article get merged with the article on Ferromagnetism? 2601:4A:4201:8520:EC81:D040:13D2:E81B (talk) 00:45, 28 August 2022 (UTC)
