This means that complementary of the fillers enhances hysteresis loss
, even though the formation and collapsing of aggregate (filler-filler accumulation) which leads to frictional energy is possible .
During excitation, when the ramping rates are 10, 5, 1, 0.5, and 0.1 A/s, the turn-to-turn losses are 5557.3, 5354.5, 4079.5, 3069.5, and 957.2 J, and the hysteresis losses
are 636.5, 618.3, 378.8, 209.7, and 101.1 J.

Therefore, it is possible to ignore the eddy current loss in magnetite nanoparticles in contrast to the hysteresis loss
The experimental output responses evaluated included the cell nucleation density, bulk density of the foam, compression hysteresis loss
, tensile strength, and Shore A hardness.
of the stator core can be calculated as:
Magnetic hysteresis loss
of unit mass is expressed as Eq.
The electrical losses of a PM AC machine include, i.e., eddy current and hysteresis losses
in the stator and rotor cores, eddy current and hysteresis loss
in the permanent magnet and copper loss of the stator winding.
Loss separation breaks the total core loss into static hysteresis loss
, classical eddy current loss, and excess loss .
is defined as the loss of energy of the specimen when deformed during a given loading-unloading cycle.
As the current reverses direction, the hysteresis loss
at specific frequencies changes significantly under strain.
Further, in certain of the enhanced elastic modulus embodiments, the rubber compositions containing the metal carboxylate also have decreased hysteresis loss
Evans, "Pyroelectric energy conversion: hysteresis loss
and temperature sensitivity of a ferroelectric material," Journal of Applied Physics, vol.
This kind of heat dissipation has been termed "hysteresis loss
." Briefly, the heat dissipation from nanoparticles with unit weight during unit time, also called specific loss power Ph, abruptly increases from zero to 4[[mu].sub.0][mu][H.sub.K] x f x [w.sup.-1] (= 4[[mu].sub.0][M.sub.s][H.sub.K] x f x [[rho].sup.-1]) when [H.sub.ac] becomes higher than [H.sub.K], where w and [[rho].sup.-1] are the weight and density of the magnetic core of the nanoparticles, respectively.
If the principle components for these losses are accounted (e.g., static hysteresis loss
, classical eddy current loss, and excess loss for [P.sub.mc] ; joint action of eddy and proximity effects for [P.sub.w]) they can be presented
