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.

Physics Right-Hand Rule: Definition & Practice

4. Physics Right-Hand Rule: Definition & Practice

Many of the equations and tools used in physics are pretty complex, but not all of them. In this lesson, we will explore physics' right-hand rule and then put it into practice.

Using the Lorentz Force Law to Examine Electric & Magnetic Forces

5. Using the Lorentz Force Law to Examine Electric & Magnetic Forces

Electricity and magnetism are closely related. Electric charges generate electric fields, and moving charges generate magnetic fields. In this lesson, we will learn how to calculate the strength of a magnetic field and use the Lorentz force law, which deals with the two forces on a charge moving through a magnetic field.

The Biot-Savart Law: Definition & Examples

6. 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.

Magnetic Forces & Fields Practice Problems

7. Magnetic Forces & Fields Practice Problems

Magnetism and electricity are closely related. When current flows in a wire, a magnetic field is generated. In this lesson, we will explore how magnetic fields can exert forces on parallel current-carrying wires.

Electromagnetic Induction: Conductor to Conductor & Transformers

8. 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.
