An automatic hysteresis loss recorder
IEE-IERE Proceedings - India, 1973The present communication describes the development of an experimental arrangement for automatic recording of hysteresis loss without making use of a cathode ray oscilloscope. A simple moving coil type d.c. meter in the proposed arrangement reads the hysteresis loss directly.

Hysteresis loss in a multifilament Superconductor
1977Calorimetric measurements of the alternating field eddy current losses in three twisted filamentary, mixed-matrix superconductors were recently reported and compared with calculated losses based on the continuum model for a multifilament conductor. The measurements and comparison are extended here to the hysteresis loss.

Hysteresis losses in a superconducting plate
Cryogenics, 1978Abstract On the basis of theoretical analysis expressions have been derived suitable for calculating the hysteresis losses in the presence of variable and constant components of both external magnetic field and transport current in a superconducting layer.

Hysteresis Loss as a Measure of Metal-Rubber Adhesion
The Journal of Adhesion, 1993AbstractAs in the case of reinforcing filler‐induced increase in hysteresis in rubbers, placement of aluminum (A1) foil to the surface of a rubber blend of epichlorohydrin rubber and carboxylated nitrile base induces increased hysteresis of the rubber due to adhesion between Al and the rubber blend.

Modeling of hysteresis and power losses in transformer laminations
IEEE Transactions on Power Delivery, 2002In this paper, a method for the representation of hysteresis and power losses in the laminations of power transformers is proposed. The developed model is based on data supplied from a steel manufacturer and able to predict hysteresis and eddy current losses.

Eddy current and hysteresis losses in ferromagnetic media
IEEE Transactions on Magnetics, 1998This paper is a contribution to the evaluation of losses in ferromagnetic media, due to eddy currents and magnetic hysteresis, the field source being the time harmonic induced e.m.f. The fundamental field equations are solved numerically by using a finite element formulation, corresponding to the space discretization, and a second order trapezoidal ...

Hysteresis losses in the Preisach framework
Empirical Economics, 2018Hysteresis is a nonlinear and path-dependent phenomenon which is used to model the “wait-and-see” behaviour of firms in times of uncertainty. Important applications are found on the labour market and foreign trade. Reasons for hysteresis in foreign trade are sunk costs e.g.

Ratio of the rotational loss to hysteresis loss in ferrimagnetic powders
IEEE Transactions on Magnetics, 1974The ratio of the rotating hysteresis loss to alternating hysteresis loss W_{r}/W_{h} is examined as a function of the magnetic field for various ferrimagnetic powders dispersed in a nonmagnetic matrix. A comparison of the W_{r}/W_{h} vs H behavior for single-domain particles with that of multidomain particles is made.

Reduced hysteresis loss in superconducting bearings
Applied Superconductivity, 1996Abstract Spin-down results are reported for a permanent magnet (PM) ring levitated in vacuum over an array of high-temperature superconductors (HTSs). A method was developed that uses a small amount of soft-ferromagnetic shims to reduce the azimuthal inhomogeneity of the PM.

Frequency dependent hysteresis loss in SiFe
Journal of Applied Physics, 1982We have studied the hysteresis loss associated with nonmagnetic inclusions that are large enough to support a supplementary domain structure. This tube domain structure interacts with a main domain wall by adhering to it as long as it is near enough to the inclusion.
