### About This Chapter

## TExES Physics/Math 7-12: Magnetism - Chapter Summary

As part of a review course for the Texas Examination of Educator Standards (TExES) Physics/Mathematics 7-12, the lesson videos in this chapter will help you re-examine the nature and uses of magnetic force. In these videos, our expert instructors will help you prepare to answer questions regarding topics such as:

- Magnetic poles and how magnetic forces affect charges
- Magnetic fields
- Uses of electromagnetic energy
- Converting electrical energy to mechanical energy
- Faraday's Law
- The Biot-Savart Law
- Ampere's Law
- Maxwell's equations

Further reinforce your understanding of the forces and uses of magnetism by working through lesson worksheets, and take quizzes to determine areas of weakness. Return to the any point of the lessons with video tags that are linked to the key information. If at any time you have a question about the chapter, ask our instructors for clarification to ensure your mastery of the material before you take the TExES Physics/Mathematics 7-12 exam.

### TExES Physics/Math 7-12: Magnetism Chapter Objectives

The lesson videos, worksheets and quizzes of this chapter have been compiled to help you prepare for the questions related to magnetism on the TExES Physics/Mathematics 7-12 exam. The assessment has 120 multiple-choice questions and is computer based. It's used to certify math/physics teachers in the state of Texas. The Physics portion of the exam accounts for 39% of the score, and questions on magnetism may be included.

### 1. Overview of Magnetic Forces & Poles

After completing this lesson, you will be able to explain what magnetic forces are and how they can be created (with ferromagnets and electric currents), and explain how we've all got the poles of the Earth backwards. A short quiz will follow.

### 2. Magnetic Field: Definition & Creation

After completing this lesson, you will be able to explain what a magnetic field is, how they are created, and suggest some uses for magnetic fields. A short quiz will follow.

### 3. Overview of Electromagnetic Induction

After completing this lesson, you will be able to explain what electromagnetic induction is and describe how it is used to generate electricity in our everyday lives. A short quiz follows the lesson.

### 4. 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.

### 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. 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.

### 7. 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.

### 8. 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.
