Several phenomena in real life that awe inspire the man kind can be understood by understanding some basic physical concepts related to electricity and magnetism. Ever wondered how toner particles form images on papers, what happens when lightning strikes an automobile, how are microphones, DJ tables and sound systems built, how batteries work and why smart phones have such a short battery life. The answer to these and many other questions can be found in this particular course. Some highlights of the physical concepts that students will get to see during this course are as follows. Introduction to Electromagnetism and Electrostatics: Electric charge, Coulomb's law Electric Field, Gauss’s law, Electrostatic Potential, Capacitors and Dielectrics, Ohms’s law, Electric currents, and electric circuits, Kirchoff laws Magnetic fields, Biot-Savart law and Ampere's law, Magnetic materials. Time-varying fields and Faraday's law of induction, The Hall effect, Displacement Current and Maxwell's equations.
