About This Chapter
Overview of Magnetism in Physics - Chapter Summary
This chapter covers magnetism in physics beginning with the definition of magnetic force and a magnetic field. Poles, dipoles, and a discussion of how magnetic forces affect moving charges are also included. After completing this chapter, you should be able to:
- Define electromagnetic induction and Faraday's Law of Electromagnetic Induction
- Understand transformers and conductor to conductor induction
- Explain the Biot-Savart Law
- Identify Ampere's Law
- Summarize Lenz's Law, magnetic flux, and motional EMF
- Apply Maxwell's equations
- Discuss Magnetic flux and current loops
The video lessons are taught by our expert instructors. The lessons are short and engaging and available on the internet whenever it is convenient for you to learn. Use the lesson quizzes and video transcripts to check your progress and further your review.
1. 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.
2. 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.
3. 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.
4. 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.
5. Faraday's Law of Electromagnetic Induction: Equation and Application
Electromagnetic induction allows us to induce voltage with the movement of a magnetic field. Credited to Michael Faraday, this discovery was not only groundbreaking at the time, but it has since led to many applications in everyday life.
6. Electromagnetic Induction: Definition & Variables that Affect Induction
We use electromagnetic induction every day, but do you have any idea what it is? In this lesson, we'll discuss this everyday phenomenon, the factors that affect its strength and its most common applications.
7. Electromagnetic Induction: Conductor to Conductor & Transformers
Every day, we make use of a special case of electromagnetic induction known as mutual induction. In this lesson, we'll talk about this special phenomenon and how it is used in many common devices.
8. The Biot-Savart Law: Definition & Examples
After watching this lesson you will be able to explain what the Biot-Savart Law is, and use the simplified version to solve problems. A short quiz will follow.
9. Ampere's Law: Definition & Examples
After watching this video, you will be able to explain what Ampere's Law is, and use Ampere's Law for a long, straight, current-carrying wire to solve problems. A short quiz will follow.
10. Lenz's Law, Magnetic Flux and Motional EMF
Did you know that you can produce electricity by simply moving a magnet? In this lesson, learn more about electromagnetic induction and how electricity is generated.
11. Maxwell's Equations: Definition & Application
After watching this video, you will be able to explain what Maxwell's equations are, the basic principles behind each one, and what benefits they have led to in society. A short quiz will follow.
12. Magnetic Flux & Current Loops
Magnetic flux is a magnetic field that penetrates a specific area. In this lesson, we will learn how a conductor in the presence of a changing magnetic flux induces an EMF causing current to flow through the conductor generating another magnetic field.
