## What are magnetic fields?

What are magnetic fields? Simply speaking a magnetic field is the region around a magnet. Magnets are made out of mineral called magnetide (or lodestone) which has the property of attracting iron. Scientists use magnetic field lines to represent these magnetic fields. The magnetic field lines of a simple magnet are shown in the picture [...]

## Measuring Magnetic Fields

Measuring Magnetic Fields After reading this section you will be able to do the following: Determine how the direction and intensity of magnetic fields can be found. Describe how a field indicator and a Hall-effect meter work. Since it is impractical to measure the actual field strength within the material, all the devices measure the [...]

## Circular Magnetic Fields: Distribution and Intensity

Circular Magnetic Fields: Distribution and Intensity After reading this section you will be able to do the following: Explain the distribution and intensity of magnetic fields around conductors Explain what the skin effect is As discussed previously, when current is passed through a solid conductor, a magnetic field forms in and around the conductor. The [...]

## Longitudinal Magnetic Fields

Longitudinal Magnetic Fields Longitudinal magnetic fields refer to magnetic fields that are oriented parallel to the direction of propagation of a wave or particle. These fields play a crucial role in various scientific and technological applications, including particle accelerators, plasma physics, astrophysics, and magnetic resonance imaging (MRI). In the context of particle accelerators, longitudinal magnetic [...]

## Electricity and Magnetism

Electricity and Magnetism After reading this section you will be able to do the following: Discuss what happens to a compass when a wire with electrical current is near. Describe the relationship between electricity and magnetism. Why does the compass respond when it is near an electrical wire with current flowing through it? We can [...]

## Electromagnetic Fields

Electromagnetic Fields After reading this section you will be able to do the following: Describe the magnetic fields that surround a current carrying conductor. Iron filings scattered in the vacinity of a current carrying wire will reveal a magnetic field perpendicular to the current flow. Magnetic field lines directed out of the page towards the [...]

## Magnetic Field Characteristics

Magnetic Field Characteristics After reading this section you will be able to do the following: Describe magnetic fields in different shaped magnets. Understand the important properties possessed by magnetic lines of force. Magnetic Field In and Around a Bar Magnet As discussed previously, a magnetic field is a change in energy within a volume of [...]

## Creation of Magnetic Fields

Creation of Magnetic Fields After reading this section you will be able to do the following: Define a magnetic field and explain how it is created. Magnetic Field Creation A magnetic field describes a volume of space where there is a change in energy. As Ampere suggested, a magnetic field is produced whenever an electrical [...]
