  Scalar fields are characterized by a magnitude, while vector fields have both magnitude and direction. This section explores the properties and applications of scalar and vector fields in electromagnetics.
• Coordinate Systems:
  Coordinate systems are used to describe the position of points in space. This topic covers Cartesian, cylindrical, and spherical coordinate systems, and explains their applications in electromagnetic field analysis.

Unit 2: Electrostatics

• Coulomb’s Law:
  Coulomb’s Law describes the force between two point charges. This section covers the vector form of Coulomb’s Law and its applications in calculating electric field intensity.
• Electric Field Intensity:
  Electric field intensity is the force exerted per unit charge. This topic covers the calculation of electric field intensity due to point charges, line charges, surface charges, and volume charges.
• Gauss’s Law:
  Gauss’s Law relates the electric flux through a closed surface to the charge enclosed by that surface. This section explains the application of Gauss’s Law in calculating electric fields in symmetrical charge distributions.
• Electric Potential:
  Electric potential is the work done to move a unit charge from a reference point to a specific point in an electric field. This topic covers equipotential surfaces and the relationship between electric field and potential.
• Electric Field in Dielectrics:
  Dielectrics are insulating materials that affect electric fields. This section explores the behavior of electric fields in dielectric materials, including polarization, dielectric constant, and dielectric strength.

Unit 3: Magnetostatics

• Magnetic Fields and Forces:
  Magnetostatics deals with magnetic fields produced by steady currents. This section covers the relationship between magnetic induction (B) and magnetic field strength (H), and the forces experienced by current-carrying conductors.
• Maxwell’s Equations for Static Fields:
  Maxwell’s equations describe the behavior of electric and magnetic fields. This topic covers the integral and differential forms of Maxwell’s equations for static fields, including their applications.
• Magnetic Scalar and Vector Potentials:
  Scalar and vector potentials are used to describe magnetic fields. This section explores the Laplace and Poisson equations for scalar magnetic potential, and the concept of vector magnetic potential.
• Inductance and Magnetic Forces:
  Inductance is a property of electrical circuits that opposes changes in current. This topic covers the calculation of inductance for different configurations, such as coils and toroids, and the forces exerted by magnetic fields.

Unit 4: Electrodynamics

• Faraday’s Law of Electromagnetic Induction:
  Faraday’s Law states that a changing magnetic field induces an electromotive force (EMF) in a closed loop. This section covers the principles and applications of electromagnetic induction.
• Lenz’s Law and Its Applications:
  Lenz’s Law describes the direction of induced currents in response to changing magnetic fields. This topic explores the applications of Lenz’s Law in electric motors, transformers, and generators.
• Maxwell’s Equations for Time-Varying Fields:
  Maxwell’s equations for time-varying fields describe the dynamic behavior of electric and magnetic fields. This section covers Ampère’s Law with Maxwell’s addition, Gauss’s Law for electric and magnetic fields, and the concept of displacement current.
• Boundary Conditions for Electromagnetic Fields:
  Boundary conditions describe the behavior of electromagnetic fields at the interface between different media. This topic covers the boundary conditions for electric and magnetic fields in time-varying situations.
• Energy and Forces in Electromagnetic Fields:
  Electromagnetic fields store and transfer energy. This section explores the concepts of energy density, Poynting vector, and the forces experienced by charges and currents in electromagnetic fields.

Unit 5: Electromagnetic Waves

• Wave Propagation and Characteristics:
  Electromagnetic waves are oscillating electric and magnetic fields that propagate through space. This section covers the characteristics of electromagnetic waves, including wave velocity, wavelength, frequency, and amplitude.
• Attenuation and Phase Constants:
  Attenuation describes the reduction in wave amplitude as it propagates through a medium. This topic covers the attenuation and phase constants, and their impact on wave propagation.
• Intrinsic Impedance and Propagation Constant:
  Intrinsic impedance is the ratio of electric to magnetic field amplitudes in a wave. This section covers the calculation of intrinsic impedance and propagation constant for different media.
• Electromagnetic Waves in Different Media:
  Electromagnetic waves behave differently in various media, including free space, dielectrics, and conductors. This topic explores the propagation of electromagnetic waves in these media and the concept of skin depth.
• Poynting Theorem and Vector:
  The Poynting theorem describes the flow of energy in electromagnetic fields. This section covers the Poynting vector and its applications in calculating power and energy transfer in electromagnetic systems.
