網頁BY CHARLES PROTEUS STEINMETZ. CHAPTER I COEFFICIENT OF MOLECUTLAR MAGNETIC FRICTION. In two former papers, of January 19 and September 2T, 1892, I have shown that the loss of energy by mnagnetic hysteresis, due to miolecular friction, can, with sufficient exactness, be expressed by the empirical formula- :I = a B16 where H = loss of … 400床 病院 規模網頁2024年2月23日 · W h = η × B m 1.6 × f × V. Where η is Steinmetz constant or hysteresis coefficient. f is frequency. B m is the magnetic flux density. V is the volume of the core. W h is hysteresis loss. ∴ The hysteresis loss in a given magnetic material may be decreased by decreasing maximum flux density established through it or by using magnetic ... 400扭矩網頁Steinmetz's Equation.
