About This Chapter
ILTS Environmental Science: Magnetism - Chapter Summary
In this chapter, the lessons provide basic information on magnetism and how it works. You will examine electromagnetic induction and what can affect it. You will also explore magnetic force. Other lessons look at magnetic fields, including their properties and impact. This chapter will help you prepare for the exam by giving you instruction on these topics:
- Electromagnetic induction: conductor to conductor and transformers
- Electromagnetic induction: definition and variables that affect induction
- How magnetic force affects moving charges
- How magnetic fields are created
- Definition of magnetic force
- Poles and dipoles
- What is a magnetic field?
Expert instructors teach the video lessons, guiding you through the topics in an entertaining manner. You'll see what you need to know in order to correctly answer the exam questions on magnetism.
Objectives of the ILTS Environmental Science: Magnetism Course
Persons who desire to teach environmental science at the secondary school level in Illinois must successfully complete the Illinois Licensure Testing System (ILTS) environmental science content area exam. This 125-question test is divided into six subareas. The questions from the Magnetism chapter are in subarea III. All questions on the test are multiple choice. The self-assessment tests found at the end of each video lesson give you a chance to check what you've learned as well as to get used to the test's format.
1. 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.
2. 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.
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.
4. 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.
5. 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.
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.
