What is a Magnetic Field?

1. 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

2. 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

3. 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.

Ferromagnetism: Definition & Examples

4. Ferromagnetism: Definition & Examples

This lesson explores ferromagnetism, the ability of a material to produce a magnetic field all by itself. We discuss which common materials are ferromagnetic, why these materials are ferromagnetic while others aren't, how processes inside the material actually create the magnetic field, and more.

Calculating Motion in Magnetic Fields: Formula & Practice

5. Calculating Motion in Magnetic Fields: Formula & Practice

Magnetic fields exert a force on moving charged particles. In this lesson, we will focus on the formula for the magnetic centripetal force acting on an electron. We will also work through some example problems.

Ampere's Law: Definition & Examples

6. 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.

Electromagnetic Force: Definition & Characteristics

7. Electromagnetic Force: Definition & Characteristics

Electromagnetic forces are important in so many ways! In this lesson, you will learn about different types of electromagnetic forces and how to calculate them.
