About This Chapter
Electrostatics and Magnetism - Chapter Summary
Video lessons in this chapter can help you brush up on and add to your knowledge of electromagnetic radiation, magnetic fields and related subjects. Reviewing these lessons will help you understand the impact of electromagnetism on the body and the concepts behind electrostatic and magnetic diagnostic tools. We have a wide range of video lessons that apply to this subject, and they include:
- Coulomb's Law (force between charged particles) and electric dipoles
- Electric charge and force, including insulators and conductors
- Electric force fields and the significance of arrow direction and spacing
- Electric potential: charge collections and volt unit
- Gauss's Law
- Magnetic field basics and how magnetic fields are created
- Magnetic force and how it affects moving charges
These video lessons use clear, everyday language and real-world examples to make the study of electrostatic and magnetic principles easier and memorable. After each lesson you will have an opportunity to complete a multiple-choice quiz to measure your lesson retention. At the end of the chapter you will be presented with an exam to test your synthesis of the concepts presented in the chapter.
1. 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.
2. 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!
3. 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.
4. Electric Potential: Charge Collections and Volt Unit
In this lesson, we'll find out that electric charges can be rather lazy until something motivates them to get work done. Find out what gives electric charges the potential to do work and how we measure that potential with something called voltage.
5. 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.
6. Finding the Electric Potential Difference Between Two Points
After watching this video, you will be able to explain what electric potential difference is and calculate the electric potential difference between two points in a uniform electric field. A short quiz will follow.
7. 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.
8. What is a Magnetic Field?
Magnetic fields fill the space around all magnets, but they're impossible to detect with our own senses. We'll use a common tool to map out a magnetic field and then discuss ferromagnetic materials to see how a magnetic field can be used to create new magnets.
9. Magnetic Force: Definition, Poles & Dipoles
You're probably familiar with magnets, but have you ever stopped to consider how they work? In this lesson, we'll look at the root of magnetism and some of the fundamental properties of magnets.
10. How Magnetic Fields Are Created
Have you ever wondered how magnetic fields are created? In this lesson, we'll discuss the very simple answer to this question and look at how electric current can be used to make electromagnets, which have many everyday applications.
11. How Magnetic Forces Affect Moving Charges
A magnetic field exerts a force on a moving charged particle in ways that you might not expect. In this lesson, we're going to look at the direction of this force and the factors that affect its strength.
