'Electromagnetic Theory' is a course offered in the third semester of B. Tech. in Electrical and Electronics Engineering program at School of Engineering, Amrita Vishwa Vidyapeetham.
Unit 1
Vectors and co-ordinate systems: Cartesian, cylindrical and spherical co-ordinate systems- scalar and vector fields.
Electric and Magnetic fields: line, surface and volume integrals - Coulomb’s law - Gauss’s law - Biot-Savart’s law - Ampere’s circuital law – applications - boundary conditions for electric and magnetic fields - Lorentz force equation.
Unit 2
Maxwell’s equations: gradient, curl and divergence - Maxwell’s equation in integral form - Law of conservation of charge - Maxwell’s equation in differential form - continuity equation - boundary condition for electromagnetic fields.
Electric potential - Poisson’s and Laplace’s equations – capacitance - energy stored - magnetic scalar and vector potentials - magnetic circuits – inductance - energy stored-conductance.
Unit 3
