This text investigates the fundamental principles governing the interaction between electrically conducting fluids and magnetic fields. Alan Jeffrey, a mathematician known for his contributions to wave propagation and differential equations, provides a rigorous framework for understanding the behavior of plasmas and liquid metals. The book synthesizes vector calculus and Maxwell's equations to establish the governing equations of magnetohydrodynamics (MHD) within a formal mathematical structure.

Experts classify this work as a concise, foundational text suitable for students transitioning into advanced fluid mechanics. Readers frequently note the mathematical density of the prose, which requires a strong background in vector analysis and partial differential equations.
