Magnetism - ORELA Middle Grades General Science - Chapter Summary

The ORELA Middle Grades General Science assessment gauges your comprehension of various science concepts. In this chapter, you can enjoy a quality review of magnetism so you're prepared to answer questions that address the following:

  • Defining magnetic force and the magnetic field
  • Explaining how magnetic fields are created
  • Discussing how magnetic forces affect moving charges
  • Sharing the meaning and variables that affect electromagnetic induction
  • Describing conductor to conductor and transformers in electromagnetic induction
  • Examining electric motors and generators

Subject-matter experts make studying fun by presenting a comprehensive overview of magnetism with the help of fun visual effects. This engaging approach to instruction can increase your confidence as you study for the exam.

Magnetism - ORELA Middle Grades General Science Chapter Objectives

The ORELA Middle Grades General Science assessment gauges educators' comprehension of science with 150 multiple-choice questions that are broken into four content domains. The topics covered in this chapter on magnetism are found in the physical science content domain, which constitutes about 31% of the total test. Preparing for questions in this domain can increase your chances of earning a minimum passing score of 228 and securing the licensure needed to teach general science to students in middle grades.

You can use the resources in this chapter to simplify the studying process. In addition to watching the video lessons, you can access transcripts that offer easy-to-identify vocabulary words. Self-assessment quizzes are also available to gauge your comprehension of the lessons.

Magnetic Force: Definition, Poles & Dipoles

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.

What is a Magnetic Field?

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.

How Magnetic Fields Are Created

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.

How Magnetic Forces Affect Moving Charges

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.

Electromagnetic Induction: Definition & Variables that Affect Induction

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.

Electromagnetic Induction: Conductor to Conductor & Transformers

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.

Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

7. Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

Both generators and electric motors are common devices in everyday life, but how do they work and what is the difference between them? In this lesson, we'll explore both of them, which may produce different results but are actually more similar than they may seem.
