About This Chapter
AP Physics 2: Magnetic Fields - Chapter Summary
Magnetic fields have an important impact on our everyday lives. Learn about these fields, how they are created, the basics of magnetic forces and ferromagnetism with help from this chapter. Engaging lessons developed by top instructors are fun to review and easy to navigate. Quizzes accompanying the lessons can quickly and effectively test your comprehension of the concepts they cover. If you hit a snag during your review or need additional information, be sure to send your questions to our experts. When finished, you will be able to:
- Define a magnetic field
- Explain how magnetic fields are created
- Discuss how moving charges are impacted by magnetic forces
- Share the definition of ferromagnetism and list common materials that are ferromagnetic
1. 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.
2. 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.
3. 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.
4. Ferromagnetism: Definition & Examples
This lesson explores ferromagnetism, the ability of a material to produce a magnetic field all by itself. We discuss which common materials are ferromagnetic, why these materials are ferromagnetic while others aren't, how processes inside the material actually create the magnetic field, and more.
