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 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.

4. The Lorentz Force Law

Electric and magnetic fields are both capable of creating forces on charged particles. In this lesson you'll learn how these two forces are related through the Lorentz force law.

5. 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.

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.

7. What is Solenoid? - Definition, Uses & Examples

In this lesson, you will learn what a solenoid is, how it relates to electromagnets, and how it is used in a few real-life situations. A short quiz will follow.

8. Diamagnetism & Paramagnetism: Definition & Explanation

In this lesson, we learn more about electron configuration through the concepts of diamagnetism and paramagnetism. We will review electron structure in an atom, and define diamagnetism and paramagnetism.

9. 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.

10. Lenz's Law, Magnetic Flux and Motional EMF

Did you know that you can produce electricity by simply moving a magnet? In this lesson, learn more about electromagnetic induction and how electricity is generated.

11. 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.
