About This Chapter
Electrical & Magnetic Forces - Chapter Summary
Use the lessons in this chapter as part of your review of what you studied in college about electrical and magnetic forces. The videos go over all the important points you need to know, including:
- The atom, electrons and protons
- Repulsion and attraction of electric force fields
- Coulomb's Law
- Qualities of good conductors and insulators
- Gauss' Law
- The Lorenz Force Law
- The right-hand rule
Our knowledgeable instructors guide you through each topic and principle to help you prepare for the test. By using a combination of video lessons and quizzes, the material is presented in multiple ways, making it easier to learn and retain.
1. Electric Charge and Force: Definition, Repulsion & Attraction
Have you ever wondered what electricity is and where it comes from? Have you ever been zapped by static electricity and wondered how it got there? We'll answer all of these questions in this lesson on electric charge and force!
2. Electric Force Fields and the Significance of Arrow Direction & Spacing
Did you know that force fields don't just exist in science fiction movies? In this lesson, we'll explore the electric force fields that surround charged particles and how we can draw diagrams that represent them.
3. Coulomb's Law: Variables Affecting the Force Between Two Charged Particles
In the 18th century, Charles Coulomb uncovered the secrets of electrostatic force between charged particles. The results of his experiments led to what is now known as Coulomb's Law, which tells us how force, charge, and distance are all related.
4. Insulators and Conductors: Examples, Definitions & Qualities
In this lesson, we'll explore the reasons that some materials conduct electrical energy with ease while others block it almost completely. We'll also talk about the property of conductivity and some everyday examples of insulators and conductors.
5. Gauss' Law: Definition & Examples
After watching this video, you will be able to explain what Gauss' Law is, derive Gauss' Law for a sphere and cylinder, and use it to solve problems. A short quiz will follow.
6. Using the Lorentz Force Law to Examine Electric & Magnetic Forces
Electricity and magnetism are closely related. Electric charges generate electric fields, and moving charges generate magnetic fields. In this lesson, we will learn how to calculate the strength of a magnetic field and use the Lorentz force law, which deals with the two forces on a charge moving through a magnetic field.
7. Physics Right-Hand Rule: Definition & Practice
Many of the equations and tools used in physics are pretty complex, but not all of them. In this lesson, we will explore physics' right-hand rule and then put it into practice.
