11EE206 ELECTROMAGNETIC FIELDS
• To understand the concepts of coordinate systems.
• To realize the electromagnetic fields, charges and currents.
• To calculate electromagnetic field distribution.
• To impart knowledge on vector fields - electrostatic and magneto static fields, electro-
dynamics and electromagnetic waves.
General Principles: Review of vector algebra-Coordinate systems-Rectangular, Cylindrical and
Spherical Coordinate Systems- Coordinate transformation-Differential Line, Surface and
Volume Elements-Line, Surface and Volume Integrals- Gradient, Divergence and Curl
Operators- Divergence Theorem- Stokes’ Theorem.
Electrostatic Fields: Field concept – Charge Distributions – Coulomb’s Law –Electric Field
Intensity- Determination of Electric Field due to Discrete, Line, Surface and Volume Charges-
Electric Potential- Relationship between Electric Field Intensity and Electric Potential– Potential
due to Electrical Dipole-Potential due to an Infinite Uniformly Charged Line-Electric Flux and
Flux Density- Gauss’ Law- Relation Between Electric Flux and Electric Field Intensity-
Electrostatic Energy- Laplace’s and Poisson’s Equations – Dielectrics –Capacitance-Boundary
Conditions at the Interface of Two Dielectrics.
Magneto Static Fields: Current density – Magnetic Flux –Magnetic Flux Density- Magnetic
Field Intensity –Relationship between Magnetic Field Intensity and Magnetic Flux density- Biot-
Savart Law –Determination of Magnetic Field due to Infinitely Long Straight Conductor,
Circular Current Loop and Rectangular Current Loop- Ampere’s Law – Determination of
Magnetic Field due to a Co-axial Cable using Ampere’s Law- Force and Torque in Magnetic
Field- Boundary Conditions at the Interface of Two Magnetic Materials-Self and Mutual
Inductances-Inductance of a Solenoid and a Toroid.
Electromagnetic fields: Displacement current – Eddy current -Faraday’s Law – Lenz’s Law –
Transformer and Motional emfs, Maxwell’s Equations.
Electromagnetic Waves: Generation – Propagation of Waves in Dielectrics – Conductors and
Transmission lines –Skin effect-Power and the Poynting Vector.
At the end of the course, student would be able to:
