PRINCIPLES OF MAGNETOSTATICS
The subject of magnetostatics—the mathematical theory that describes the forces
and fields resulting from the steady flow of electrical currents—has a long history.
By capturing the basic concepts, and building toward the computation of mag-
netic fields, this book is a self-contained discussion of the major subjects in
magnetostatics.
Overviews of Maxwell’s equations, the Poisson equation, and boundary value
problems pave the way for dealing with fields from transverse, axial, and periodic
magnetic arrangements and assemblies of permanent magnets. Examples from
accelerator and beam physics give up-to-date context to the theory. Furthermore,
both complex contour integration and numerical techniques (including finite dif-
ference, finite element, and integral equation methods) for calculating magnetic
fields are discussed in detail with plentiful examples.
Both theoretical and practical information on carefully selected topics make this
a one-stop reference for magnet designers, as well as for physics and electrical
engineering students.
richard c. fernow received his PhD at Syracuse University for work on
particle physics and worked at Brookhaven National Laboratory. He contributed
to the optimization of the coil design for collider magnets and made calculations of
magnetic fields in solenoid channels. He is a member of the American Physical
Society.
