VERY VERY VERY...EXTENSIVE. Introduction to Hysteresis Course "...The mathematical theory of systems with hysteresis is an exiting new chapter of nonlinear analysis. While based on physical ideas, it also extends them to abstract science, enabling the analysis to be of quite general character. It includes interesting new mathematics and has a wide range of applications in science, engineering and economics..."

Sethna, Laboratory of Atomic and Solid State Physics, Department of Physics, Cornell University Multimedia Hysteresis and Avalanches Lessons, Calculators & Applets (Text & Images). VERY EXTENSIVE. Hysteresis and Avalanches "...hysteresis loops often consist of many small jumps. These jumps can be thought of as the jerky motion of a domain boundary, or as an avalanche of many local spins or domains..." Hysteresis and Avalanches Calculators include: "...Three Dimensions: Cascade; Two Dimensions: Large Randomness; The Infinite Avalanche: Three Dimensions; etc..." For more information see What's Hysteresis?; James P. Sethna's Home Page; Laboratory of Atomic and Solid State Physicsor the Department of Physics HYSTERESIS APPLET - P. Houle, Honeylocust Media Systems VERY EXTENSIVE. Hysteresis Simulation "...simulates hysteresis using a random-field ising model developed by Jim Sethna and his group. You can run our model at three different values of the random field, which determines the influence of disorder on the system..." For more information see Honeylocust Media Systems
