This book deals with theoretical thermodynamics and the statistical physics of electron and particle gases. While treating the laws of thermodynamics from both classical and quantum theoretical viewpoints, it posits that the basis of the statistical theory of macroscopic properties of a system is the microcanonical distribution of isolated systems, from which all canonical distributions stem.

As with galvanomagnetic phenomena, thermomagnetic effects are caused by the action of a magnetic field on moving particles that carry electric charges—that is, electrons in conductors and electrons and holes in semiconductors.

Before advancing the theory behind the observed anomalous results, it is instructive to present known thermoelectric effects as phenomena produced by electrical carriers behaving as if they were in a gas phase [20,21].

An algorithm is constructed for calculating the effective conductivity tensor of polycrystals in a magnetic field from the values of the galvanomagnetic characteristics of crystallites.

The algorithm is based on a series expansion in powers of the deviations of the tensors from their average values. The effective conductivity tensor is calculated in two limiting cases: in a weak magnetic field Cited by: 1. Ferrofluids can be used to transfer heat, since heat and mass transport in such magnetic fluids can be controlled using an external magnetic field.

Lastly, part four introduces the relation between physics and information theory, which constitutes a new frontier in fundamental research. The book includes step-by-step exercises, with solutions, to help readers to gain a fuller understanding of the subjects, and also features a series of appendices providing useful mathematical formulae.

This book grew out of a month-long workshop on Magnetic Reconnection Theory held in at the Isaac Newton Institute, Cambridge, UK, organized by E. Priest, T. Forbes, and J. Birn. A temperature difference across an electric conductor can generate an electric field.

This phenomenon, called the Seebeck effect, lies at the root of thermoelectricity (heat turned into electricity), and is used to drive space probes and power thermoelectric generators, and could be implemented for heat-harvesting in power plants, wrist-watches and microelectronics.
