About This Chapter
Who's it for?
This unit of our AP Physics 2 Homeschool course will benefit any student who is trying to learn about magnetic forces. There is no faster or easier way to learn about magnetism. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about magnetic fields, electromagnetic induction and electric motors and generators.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need a physics curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and a physics unit exam confirm understanding or identify any topics that require review.
Magnetism Unit Objectives:
- Learn about magnetic force and poles.
- Discover what magnetic fields are and how they're created.
- Explore the effect magnetic forces have on moving charged particles.
- Understand the variables that impact electromagnetic induction.
- Examine how one conductor's current can cause a voltage in another conductor.
- Understand Faraday's law of electromagnetic induction.
- Learn how electric generators and motors convert energy.
1. Electric Motors & Generators: Converting Between Electrical and Mechanical Energy
Both generators and electric motors are common devices in everyday life, but how do they work and what is the difference between them? In this lesson, we'll explore both of them, which may produce different results but are actually more similar than they may seem.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
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.
