Principles of Electricity & Magnetism - Chapter Summary
Our enriching lessons cover the principles of electricity and magnetism for your perusal on any mobile device or computer. Just a few of the topics presented here include electric force, electric fields, and the relationship between electric charge and force. This chapter is designed to assist you in achieving the following objectives:
- Discuss the strength of an electric field and Coulomb's law
- Explore Gauss' law
- Detail how a magnetic field works
- Explain magnetic flux and current loops
- Describe the way magnetic forces impact moving charges
- Examine electric and magnetic forces using the Lorentz force law
- Provide the definition of the physics right-hand rule
- Outline the relationship between electric and magnetic phenomena
Our thorough and interesting lessons help make this topic fun so that you can do well on a test or homework assignment. Feel free to go back and work at your own pace in order to fully understand these subjects. We've included quizzes with our lessons and a test at the end of the chapter to ensure you've fully grasped what you've studied.
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.
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!
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.
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.
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.
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.
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.
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.
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.
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.
