Introduction to Magnetism and Magnetic Materials

David Jiles' latest revision is excellent. The subject of magnetism as related to materials is covered in an interesting and useful way: by asking questions and then answering them. Latest edition is more thorough and more clearly written. Text can be used for teaching or as a reference for engineers utilizing magnetic materials in their designs.

Very in-depth book with a treasure of material properties and information that has already saved me time and money.

Equations within this edition suffer from inconsistent use of notation for constants, lapses of vector bold typeface, erroneous use of signs, incorrect definitions of what is being described, incorrect references to equations and some of them missing terms.I've compiled an errata up to page 260.On pages 14 and 34, the torque value tau should be in bold font, as shown on page 31 and 35 ( another name for the cross product is a vector product, as the result is a vector ).On page 14, "Equation 1.6" should read "Equation 1.16".On page 40. "The flux density phi" should read "The flux phi" as the symbol is phi and not B.Equation (2.75) on page 55 is incorrect. The limits of integration should read 0 / d , 0 / l respectively.The integration in (2.76) is actually ro^2/8p (dB/dt)^2, so d^2/32 (dB/t)^2 gives the former when substituting d with 2ro in the latter ( this gives 4ro^2 ). Additional steps could have been given to make this clearer.On page 87 "Mo = nm" should read "M = Nm" for consistency. The Glossary of Symbols in the beginning pages indicate that n is "The number of turns per unit length on solenoid" and N as "The number of atoms per unit volume".The same should apply to equation (4.10) on page 102 as shown in (4.9) and (9.30).On page 166, equation (7.29) "E" should be replaced with "delta E" as correctly stated, it's a change in energy.Equation (7.30) is stated as force "F", but the term "1/A" has been introduced which means this should read as pressure "p".On page 171, "domain-wall surface, energy" should read "domain-wall surface energy,"On page 201, equation (8.65) "dM/dt = -gamma tau" is described as 'change of magnetization to be proportional to the torque tau". This should be read as "torque density tau" as tau is stated here as "M x H" ( M = m/V , definition of torque t = m x H ). Tau should also be bold typeface.Typo on page 203. "pining" should be "pinning".Incorrect referenced equation on page 205. "(Equation 8.66)" should be "(Equation 8.70)".On page 214, equation (9.2) is missing a negative sign. See (10.2).On page 215, equation (9.4) has one too many negative signs. Equation (9.11) is missing the term "H".On page 250, the y-axis label on the top chart "Cal ( deg^-1 mole^-1 )" should be "Cm ( cal deg^-1 mole^-1 )".I would liked to have seen sections such as magnetic circuits, Rayleigh loops and some aspects of critical phenomena covered in more detail. But that's a personal preference.Good material can be found in this book, but for me, it's been a little frustrating in unraveling some of it's parts. I found myself questioning the validity of equations and spent a deal of time cross referencing them due to encountering the errors mentioned.The use of more diagrams would have been helpful especially when cosine terms are introduced, to aid in visualization.It's unfortunate that the proof reading of this edition was not up to a high standard. But having said that, the pedagogical structure and references have been helpful to increase my understanding of the subject and is worthy to stand along with my other volumes on magnetism.Hopefully the 4th edition won't suffer from poor quality proof reading.
