?
This book entitled “Fundamentals of Electromagnetics” presents the basic concepts of electromagnetic field. One of the main objectives of this book is to provide the students a clear and logical presentation of basic concepts and principles of electromagnetic fields. The various concepts of the subject are explained through simple reader friendly language. Large numbers of problems with their step by step solutions are provided to ease the understanding of difficult topics. The classroom experience and the difficulties of students while teaching this subject have been taken into account. The book is broadly classified into three categories— static electric field, steady magnetic field and time varying field. Study of static electric field is explained from chapter 1 to chapter 6. Chapter 7 concentrates on steady magnetic field while chapter 8, 9 and 10 focus on time varying field.

  • Chapter 1

    Vector Analysis Price 2.99  |  2.99 Rewards Points

    The electromagnetic field is study of relationship between electricity and magnetism and leads to four Maxwells equations which form the basics of electromagnetics. As the electromagnetic wave propogates in space, it deals with the space and to study this three dimentional view, it is necessary to study the co-ordinate system. In this chapter, we shall study the concepts of vector algebra, vector calculus and co-ordinate system.
  • Chapter 2

    Coulombs Law and Electric Field Intensity Price 2.99  |  2.99 Rewards Points

    The electromagnetic field is the combined effect of electric and magnetic field. We have studied effect of these two fields in vacuum or free space separately. In this chapter we shall study the static electric field. The steady magnetic field will be introduced in Chapter 7. While the time varying field will be introduced in Chapter 8. We shall start with the basic law of electrostatics i.e., coulomb’s law.
  • Chapter 3

    Electric Flux Density Gausss Law and Divergence Price 2.99  |  2.99 Rewards Points

    In the last chapter, we shall study that an electric field is set up around a point charge Q. So these electric field lines originate from a point charge Q and these electric field lines or lines of force are called electric flux and is equal to charge Q itself. The electric flux per unit area is defined as electric flux density D. In this chapter we start with this basic of electric flux and then study Gauss’s law and divergence theorem. For better understanding of concept of electric flux, we start with faraday’s experiment.
  • Chapter 4

    Energy and Potential Price 2.99  |  2.99 Rewards Points

    In chapter 2, we have studied Coulomb’s law and its use in finding the electric field intensity due to simple charge distribution. Also by Gauss’s law, the problem get simplified for symmetrical distribution when proper closed surface was chosen. This electric field intensity is also related with the scalar quantity called electric potential and it is possible to determine the electric field from potential by a new concept called gradient. In this chapter initially we start with the concept of electric potential and find the relation between electric field intensity Eand electric potential V.
  • Chapter 5

    Conductors and Dielectric Price 2.99  |  2.99 Rewards Points

    Uptil now we have studied the electrostatic fields in free space or vaccum that has no materials in it. In this chapter we shall study the electric fields in material media like conductors and dielectrics. For that we first start with the properties of materials like conductor and dielectric.
  • Chapter 6

    Poissons and Laplace Equation Price 2.99  |  2.99 Rewards Points

    In earlier chapters, we determined that E and D in the given region by using Coulomb’s law and Gauss’s law or using E = – V  when the potential V is known throughout the region. In this chapter, we shall study the electrostatic boundary value problems. In this the electrostatic conditions are known at some boundaries of the region and it is desired to find E and V throughout the region. Such problems are solved by using Poisson’s and Laplace equation.
  • Chapter 7

    The Steady Magnetic Field Price 2.99  |  2.99 Rewards Points

    Uptil now, we have studied the electrostatic field produced by static or stationary charges. In this chapter we shall study the steady magnetic field or magnetostatic field. The source of steady magnetic field may be a permanent magnet, an electric field changing linearly with time, or a direct current. Here we shall study the steady magnetic field due to direct current. There are two major laws governing the magnetostatic fields (i) Biot-savart law—it is like Coulomb’s law of electrostatics. (ii) Ampere’s circuital law—it is like Gauss’s law of electrostatics and is easily applied to problems involving symmetrical current distribution.
  • Chapter 8

    Maxwells Equations for Time Varying Field Price 2.99  |  2.99 Rewards Points

    Upto last chapter, our discussion is restricted to static field, the field which is not changing with time. In static field, the electric and magnetic fields are independent of each other. Thus electrostatics and magnetostatics are two independent branches. But in time varying field, they are related with each other, a time varying electric field necessarily involves a corresponding time varying magnetic field. So Dynamics involves time varying fields induced by time varying sources. In this chapter we shall derive the Maxwell’s equation for time varying field.
  • Chapter 9

    Electromagnetic Wave Propagation Price 2.99  |  2.99 Rewards Points

    In this chapter we shall study the application of Maxwell’s equation to electromagnetic wave propagation. Electromagnetic wave was investigated by Heinrich Hertz. Typical example of electromagnetic wave include radiowaves, T.V. signals, radar beams.
  • Chapter 10

    Waves at Boundary Between Two Media Price 2.99  |  2.99 Rewards Points

    In previous chapter we have studied the electromagnetic wave which is propagating in a single medium. When electromagnetic wave is transmitted from one medium may meet the another medium, the wave is partly reflected and partly transmitted. In this chapter we shall study two cases for the waves at boundary between two media. First is wave incident normally and second is wave incident obliquely on boundary of two media.
