Throughout the world scientists are trying to understand the mystry of creation of this Universe and its behaviour thereafter. Complete behaviour of various stellar and Planetary processes are not easy to understand. Complex interaction of electromagnetic field and fluid dynamic field is to be understood properly. Magnetofluiddynamics (MFD)is the branch where we study such interactions. This book presents a coherant, comprehensive account of fundamentals of Magnetofluiddynamics. The book discusses some nice methods of dealing with the Magnetofluiddynamic problems. Various techniques are dealt in crisp language with clear thought and in rigorous mathematical expositions. This book is unique in more ways than one and will help students as well as researchers of Theoretical Physics and Applied Mathematics.
