About This Chapter
Below is a sample breakdown of the Magnetism chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.
|Day||Topics||Key Terms and Concepts Covered|
|Monday||Magnetic forces and fields||Definitions for the following: magnetic force, magnetic field, poles, and dipoles; how to create magnetic fields; and, how moving charges are influenced by magnetic forces|
|Tuesday||Electromagnetic induction||Describe the concept of induction, point out variables that can impact induction, analyze how current in one conductor can create voltage in a separate conductor, and explain the purpose of transformers|
|Wednesday||Generating energy||Electrical energy, mechanical energy, electric motors, generators, and converting between different types of energy|
|Thursday||Magnetism laws and formulas: Part I||Faraday's Law of electromagnetic induction, the Biot-Savart Law, and related examples|
|Friday||Magnetism laws and formulas: Part II||Ampere's Law, Maxwell's Equations, practice equations, and real-world application scenarios|
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. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
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.
