An iron or steel wire subjected to longitudinal magnetisation by a surrounding solenoid gave when twisted a current along itself, which was observed by means of a ballistic mirror galvanometer in circuit with the wire. When the twist was that of a common screw the transient current flowed along the wire from the nominal N. to the nominal S. end. An opposite twist gave an oppositely directed current. 

Large-scale computer investigations of finite-temperature nucleation and growth phenomena in magnetization reversal and hysteresis (invited)

An overview of some of the results obtained from long-time dynamic simulations of models of magnetic nanoparticles and thin magnetic films is presented. The simulation methods include dynamic Monte

Control of hysteretic systems through inverse compensation

Inverse compensation is a fundamental technique in the control of systems with hysteresis. In this expository article, we present algorithms for constructing the inverse of the Preisach operator, a

Hysteresis is a special type of behavior encountered in various fields of science and engineering. In civil engineering and smart structures, the Bouc–Wen model has been used extensively to represent

Hydraulic Properties and Non-equilibrium Water Flow in Soils

Accurate knowledge of hydraulic properties for unsaturated soils is critical in the estimation of soil water fluxes by simulation models that are based on the Richards equation. The purpose of this

Hysteretic moisture properties of porous materials: Part I: Thermodynamics

This article develops a thermodynamic description of hysteretic behaviour of moisture in materials. The moisture sorption is described by a ‘condensation potential’ using a ‘pore interaction energy’

Force fields, hysteresis and economic equilibria

Looks at the relevance to economic systems of force field equilibrium metaphors. Points out that the force field view of physical reality developed in nineteenth century physics does not necessarily

Thermal hysteresis in isomorphic divalent ionic nitrates Ba(NO3)2, Pb(NO3)2, and Sr(NO3)2

Dielectric constant e and dc resistivty ϱdc measurements of the divalent nitrates Ba(NO3)2 Pb(NO3)2, and Sr(NO3)2, show the existence of thermal hysteresis accompanying the phase transformations

A Survey of the Hysteretic Duhem Model

The Duhem model is a simulacrum of a complex and hazy reality: hysteresis. Introduced by Pierre Duhem to provide a mathematical representation of thermodynamical irreversibility, it is used to

Modeling and control of hysteresis

The five articles in this special issue focus on the modeling and control of hysteresis. Hysteresis is a nonlinear effect that arises in diverse disciplines ranging from physics to biology, from
