About This Chapter
Introduction to Magnetism - Chapter Summary
The lessons in this chapter examine foundational concepts in the scientific field of magnetism. You'll learn about principles of magnetic force as well as their relationship to electric charge and related magnetic components. These lessons come with practice quizzes allowing you to monitor your understanding of each topic before moving on, making it easy to confirm your retention of information such as:
- How poles and dipoles react
- How magnetic fields are structured and function
- How magnetic fields are created
- What the impact of magnetic fields on charged particles is
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.
