This is a calculus based electromagnetism course which goes into the details of dielectric and magnetie materials under electric and magnetic fields. The course presents boundary values problems and Maxwell's equations in their local and integral forms. In this chapter we covered Faradays law of electromagnetic induction

Includes detailed explanation of Electric charges and its dipoles, electric potential energy gauss's law, and from magnetism Hall effect, lenz's law, AC generators and current LC oscillations RL,RC and LCR circuits

This document summarizes Matric IEB electromagnetism. It clearly explains and shows the hand rules as well as how motors work as well as AC generators. Faradays Law of electromagnetic induction is included as well as the right hand wire rule, right hand solenoid rule and left hand motor rule. It also summarizes the differences between generators and motors.
