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.

The Biot-Savart Law: Definition & Examples

7. 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.

Ampere's Law: Definition & Examples

8. 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.

Maxwell's Equations: Definition & Application

9. 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.

Faraday's Law of Electromagnetic Induction: Equation and Application

10. 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.

Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

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.

Calculating Equivalent Capacitance

12. Calculating Equivalent Capacitance

After watching this video, you will be able to explain what capacitance is, explain how and why capacitors work, and calculate the total (or equivalent) capacitance of a parallel or series circuit. A short quiz will follow.

What is Magmatism? - Definition, Process & Types

13. What is Magmatism? - Definition, Process & Types

When you see smoke rising from a volcano or you touch a piece of granite, you are experiencing the effects of magmatism, which is the formation and motion of magma under the surface of the earth's crust. In this lesson, learn all about magmatism and its effects on the earth.
