How Magnetic Fields Are Created

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.

Physics Right-Hand Rule: Definition & Practice

2. Physics Right-Hand Rule: Definition & Practice

Many of the equations and tools used in physics are pretty complex, but not all of them. In this lesson, we will explore physics' right-hand rule and then put it into practice.

Using the Lorentz Force Law to Examine Electric & Magnetic Forces

3. Using the Lorentz Force Law to Examine Electric & Magnetic Forces

Electricity and magnetism are closely related. Electric charges generate electric fields, and moving charges generate magnetic fields. In this lesson, we will learn how to calculate the strength of a magnetic field and use the Lorentz force law, which deals with the two forces on a charge moving through a magnetic field.

The Biot-Savart Law: Definition & Examples

4. 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.

How to Calculate Magnetic Fields from Currents

5. How to Calculate Magnetic Fields from Currents

Electric current generates a magnetic field. In this lesson, we'll investigate how to determine the direction of a magnetic field based on current direction and the strength of the field based on the current value and its distance from the wire.

Lenz's Law, Magnetic Flux and Motional EMF

6. 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.

Electromagnetic Induction: Conductor to Conductor & Transformers

7. 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.

How to Calculate Induction Currents, Voltage & Loops

8. How to Calculate Induction Currents, Voltage & Loops

When closed loop conductor experiences a change in magnetic flux, a voltage is produced, which induces an electrical current. In this lesson, we will investigate how voltages and electrical currents are generated by changes in magnetic flux.
