AFOQT: Magnetism - Chapter Summary

In this chapter, instructors help you prepare for the AFOQT exam by introducing you to the concepts you need to know about magnetic fields and magnetism processes. After reviewing the lessons, you should be able to accurately answer questions about:

  • Poles & dipoles
  • Electromagnetic induction
  • Definition & variables that affect induction
  • Creation of magnetic fields
  • Magnetic fields

Each video lesson is taught by a professional instructor who breaks down magnetism concepts in a way that makes the information accessible. The assessments, which cover important information from the lessons, can be taken online or printed so that you have a concrete document to study. As you prepare for the test, you can also use the ask-an-expert feature to get extra help when needed.

Magnetic Force: Definition, Poles & Dipoles

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.

What is a Magnetic Field?

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.

How Magnetic Fields Are Created

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.

Electromagnetic Induction: Definition & Variables that Affect Induction

4. 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.

Electromagnetic Induction: Conductor to Conductor & Transformers

5. 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.
