Book excerpt: ABSTRACT: Inductors and transformers are electrical devices critical to power conversion systems. The current-voltage (I-V) behavior of these devices is very nonlinear as a result of the magnetic cores used in their construction. However, in the design of these power conversion systems the present state of Spice-based models is limited to low frequency and room temperature effects. An addition to the present model found in many Spice type environments, Jiles-Atherton, is the subject of this work. Chapter 1 of this dissertation introduces the source of these nonlinearities as being a result of the relationship between the magnetic flux density, B, and the applied magnetic field, H. Chapter two then derives the original mathematical model used in the Spice, Jiles-Atherton, to provide a physical basis of the addition to the model. The original derivation as it can be found in the referenced literature shows that a temperature and frequency dependence on the model does not exist. This work will seek to add such a dependence on temperature first followed by frequency. Using this approach, the temperature dependence can be modeled without the core experiencing self-heating. The model therefore must be capable of being further modified after the temperature dependence is added.

Book Synopsis Hysteresis in Magnetism by : Giorgio Bertotti
Download or read book Hysteresis in Magnetism written by Giorgio Bertotti and published by Academic Press. This book was released on 1998-05-21 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive treatment of the physics of hysteresis in magnetism and of the mathematical tools used to describe it. Hysteresis in Magnetism discusses from a unified viewpoint the relationsof hysteresis to Maxwells equations, equilibrium and non-equilibrium thermodynamics, non-linear system dynamics, micromagnetics, and domain theory. These aspects are then applied to the interpretation of magnetization reversal mechanisms: coherent rotation and switching in magnetic particles, stochastic domain wall motion and the Barkhausen effect, coercivity mechanisms and magnetic viscosity, rate-dependent hysteresis and eddy-current losses. The book emphasizes the connection between basic physical ideas and phenomenological models of interest to applications, and, in particular, to the conceptual path going from Maxwells equations and thermodynamics to micromagnetics and to Preisach hysteresis modeling. The reader will get insight into the importance and role of hysteresis in magnetism; In particular, he will learn: which are the fingerprints of hysteresis in magnetism which are the situations in which hysteresis may appear how to describe mathematically these situations how to apply these descriptions to magnetic materials how to interpret and predict magnetic hysteresis phenomena observed experimentally

Book Synopsis Environmental Magnetism by : Mark Evans
Download or read book Environmental Magnetism written by Mark Evans and published by Elsevier. This book was released on 2003-06-23 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetism is important in environmental studies for several reasons, the two most fundamental being that most substances exhibit some form of magnetic behavior, and that iron is one of the most common elements in the Earth's crust. Once sequestered in a suitable material, magnetic particles constitute a natural archive of conditions existing in former times. Magnetism provides a tracer of paleo-climatic and paleo-environmental conditions and processes.Environmental Magnetism details the occurrence and uses of magnetic materials in the natural environment. The first half of the volume describes the basic principles. The second half discusses the applications of magnetic measurements in various environmental settings on land, in lakes, in the ocean, and even various biological organisms. * Material is broadly applicable to environmental studies* Case histories illustrate key points* Extensive bibliography makes further research quick and easy

Download or read book Characterization and Measurement of Magnetic Materials written by Fausto Fiorillo and published by Academic Press. This book was released on 2004-12-07 with total page 667 pages. Available in PDF, EPUB and Kindle. Book excerpt: Correct and efficient measurements are vital to the understanding of materials properties and applications. This is especially so for magnetic materials for which in last twenty years, our understanding and use have changed dramatically. New or improved materials have been created and have reached the market. The Soft amorphous alloys, the Fe-based rare-earth magnets and the giant magnetorestrictive and magnetoresistive materials have all posed challenges to measurement. At the same time new digital measurement techniques have forced a change in laboratory and commercial measuring setups. A revision of measuring standards also occurred in the 1990s with the result that there is now a lack of up-to-date works on the measurement of magnetic materials. The basic objective of this work is to provide a comprehensive overview of the properties of the hard and soft magnetic materials relevant to applications and of thoroughly discussing the modern methodologies for employed in the measurement of these properties. The balance of these topics results in a complete text on the topic, which will be invaluable to researchers, students and practitioners in industry. It will be of significant interest not only to scientists working in the fields of power engineering and materials science but also to specialists in measurement who be able to easily find all the information they need. Comprehensive overview of the properties of the hard and soft magnetic materials Provides applications and discusses thoroughly the modern methodologies for employed in the measurement of these properties Provides the latest up-to-date works on the measurement of magnetic materials
