Students will review:
This chapter helps students review the concepts in a Magnetism unit of a standard college physical science course. Topics covered include:
- Poles and dipoles of magnetic force
- Magnetic fields
- How magnetic forces affect moving charges
- Electromagnetic induction
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.
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.
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.
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.
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.
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.
