This course will provides the fundamentals of electrostatics, magnetostatics, electromagnetic induction, and electromagnetic waves.
The concepts of electromagnetism is essential to study earth and planetary sciences. The aim of this course is to understand various electromagnetic phenomena using Maxwell's Equations.
Upon completion, students will be able to
1) explain the physical meaning of the equations for electromagnetic fields written in differential forms
2) derive the distribution of electric and magnetic fields under given distributions of the charge and electric current.
3) explain the concepts of macroscopic electromagnetics and apply them to specific problems
4) calculate the propagation and of electromagnetic waves using Maxwell's equations
electric field, electrostatic potential, Gauss's law, Poisson's equation, electric dipole, magnetic field, vector potential, Ampere's law, magnetic dipole, electromagnetic induction, displacement current, electromagnetic energy, Maxwell's equations, electromagnetic wave, dielectric and magnetic materials
