About This Chapter
Magnetic Effect of Current- Chapter Summary
These lessons will address significant information about magnetic effect of current, including the origin of magnetic fields and the influence of magnetic forces on moving charges. You can explore examples of the Biot-Savard Law and learn about motional electromagnetic force. The lessons are aimed at helping you to:
- Recall how magnetic fields are created
- Identify what the Biot-Savart law is
- Understand the relationship between solenoids and electromagnets
- Review the factors that affect magnetic forces
- Learn more about electromagnetic induction
- Provide an example of a magnetic force between two parallel conductors
- Explore the conversion process into ammeter and voltmeter
We have knowledgeable and professional instructors teaching the lessons in this chapter. Multiple-choice quizzes accompany each lesson, giving you the chance to test your knowledge on the topics that you are studying. You can take these quizzes as many times as you need to until you feel confident that you have mastered the material in the chapter.
1. 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.
2. The Biot-Savart Law: Definition & Examples
After watching this lesson you will be able to explain what the Biot-Savart Law is, and use the simplified version to solve problems. A short quiz will follow.
3. 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.
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. Lenz's Law, Magnetic Flux and Motional EMF
Did you know that you can produce electricity by simply moving a magnet? In this lesson, learn more about electromagnetic induction and how electricity is generated.
6. Magnetic Force Between Two Parallel Conductors
Electricity and magnetism are closely related. There are many interesting phenomenon resulting from the two. In this lesson, we will investigate how a magnetic force acts on parallel current-carrying conductors.
