7 Lessons in Chapter 10: GED Science - Magnetism: Homework Help
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.

How Magnetic Forces Affect Moving Charges

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.

Electromagnetic Induction: Definition & Variables that Affect Induction

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.

Electromagnetic Induction: Conductor to Conductor & Transformers

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.

Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

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.
