Ch 16: Interactions of Fields in Physics

About This Chapter

With the short lessons and multiple-choice quizzes in this chapter, you should be able to obtain a better understanding of the interactions of fields in physics. Lessons on topics including magnetic force, magnetic field and gravitational field can help you get ready for an exam or complete a physics homework assignment.

Interactions of Fields in Physics- Chapter Summary

The lessons in this chapter were specially designed and made to help you better understand the interactions of fields in physics, covering topics such as force field, gravitational field and electric fields. You can look at the parts of an electromagnet, find out uses for a solenoid and explore examples of electric fields. One lesson gives an in-depth look at Newton's Law of Gravitation and examples of how it works. The lessons help you meet the following objectives:

  • Provide examples of force fields
  • Review the fundamental elements of magnets
  • Learn how a magnetic field creates new magnets
  • Recall the equations related to the gravitational field
  • Identify the different types of electric fields
  • Describe the relationship between electricity and magnetism
  • Discover what potential energy is and its uses
  • Explain what solenoid is and its uses

Force Field: Definition, Theory & Example

1. Force Field: Definition, Theory & Example

If you're a fan of science fiction, you may be familiar with a type of force field. But the idea of force fields is also used in physics. Use this lesson to learn about force fields, along with scalar and vector fields, and see some examples of each.

Magnetic Force: Definition, Poles & Dipoles

2. 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?

3. 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.

Gravitational Field: Definition & Formula

4. Gravitational Field: Definition & Formula

This lesson defines what a gravitational field is and some practical examples encountered in the real world. We also develop the equations governing the gravitational field and explain what the units of measurement mean.

Electric Fields: Definition & Examples

5. 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.

Electricity & Magnetism: Definition & Relationship

6. Electricity & Magnetism: Definition & Relationship

Electricity and magnetism are two things that seem different, but actually have a lot in common. In this lesson, we'll define each of them, and then explore how they are really part of the same fundamental force of nature.

Electric Force Fields and the Significance of Arrow Direction & Spacing

7. Electric Force Fields and the Significance of Arrow Direction & Spacing

Did you know that force fields don't just exist in science fiction movies? In this lesson, we'll explore the electric force fields that surround charged particles and how we can draw diagrams that represent them.

Newton's Law of Gravitation: Definition & Examples

8. Newton's Law of Gravitation: Definition & Examples

This lesson explains how gravity works mathematically and teaches you how to use Newton's Law of Gravitation to solve problems. A short quiz will follow.

Gravitational Attraction of Extended Bodies

9. Gravitational Attraction of Extended Bodies

After watching this lesson, you will be able to explain what an extended body is, understand the derivation for the force of gravity between a point charge and a long, thin bar and solve problems using the result of that derivation.

Electric Potential Energy: Definition & Formula

10. Electric Potential Energy: Definition & Formula

After watching this video, you will be able to explain what electric potential energy is and use an equation to solve electric potential energy problems involving point charges. A short quiz will follow.

What is an Electromagnet? - Definition, Uses & Parts

11. What is an Electromagnet? - Definition, Uses & Parts

In this lesson, you'll learn what an electromagnet is, how it is used in a few real-life situations, and the parts that make it up. A short quiz will follow.

What is Solenoid? - Definition, Uses & Examples

12. 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.
