Electric Force: Definition & Equation

1. Electric Force: Definition & Equation

The electric force is one of the most powerful, fundamental forces in the universe. In this lesson, we will learn how charged objects exert electric forces on each other and how to calculate the strength of that force.

Electric Charge and Force: Definition, Repulsion & Attraction

2. Electric Charge and Force: Definition, Repulsion & Attraction

Have you ever wondered what electricity is and where it comes from? Have you ever been zapped by static electricity and wondered how it got there? We'll answer all of these questions in this lesson on electric charge and force!

Electric Fields: Definition & Examples

3. Electric Fields: Definition & Examples

Learn what an electric field is, the types of electric fields, and the concept of electric field strength. Briefly investigate specific examples of the types of electric fields.

Strength of an Electric Field & Coulomb's Law

4. Strength of an Electric Field & Coulomb's Law

After watching this lesson, you will be able to explain what an electric field is, distinguish between scalar and vector fields and use two electric field equations to solve problems. A short quiz will follow.

Gauss' Law: Definition & Examples

5. Gauss' Law: Definition & Examples

After watching this video, you will be able to explain what Gauss' Law is, derive Gauss' Law for a sphere and cylinder, and use it to solve problems. A short quiz will follow.

What is a Magnetic Field?

6. 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.

Magnetic Flux & Current Loops

7. Magnetic Flux & Current Loops

Magnetic flux is a magnetic field that penetrates a specific area. In this lesson, we will learn how a conductor in the presence of a changing magnetic flux induces an EMF causing current to flow through the conductor generating another magnetic field.

How Magnetic Forces Affect Moving Charges

8. 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.

Using the Lorentz Force Law to Examine Electric & Magnetic Forces

9. 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.

Physics Right-Hand Rule: Definition & Practice

10. 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.
