Electric Charge and Electromagnetism

In this title, we will be looking at electric charge and how it can be produced by friction, when two different materials are rubbed against each other. We will discuss the reason why some materials, called conductors, allow electric charge to pass through them and why others, called insulators, do not. Static electricity is charge that is not moving. It can be very useful or it can be very dangerous, and we will look at the reasons for this. We will also discuss the forces that exist between like and unlike electrostatic charges. Positive and negative electrostatic charge will be considered, as well as how a force is produced when a current flows through a conductor in a magnetic field. We will then see how this can be developed to make an electric motor.
