# Electromagnetic Theory

### Overview

Instructor: Professor D.K. Ghosh, Department of Physics, IIT Bombay.

The course is a one semester first course on Electromagnetic Theory at B.Sc. level. This course would be a prerequisite for the advanced level course at the M. Sc. Level.

The course begins with a review of vector calculus which is extensively used in the course. The course covers electrostatics, magnetostatics, electromagnetic induction and electromagnetic waves. At the end of this course, a student is expected to be familiar with both the differential and integral forms of Maxwell's equations.
