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

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 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

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

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 [...]

  • Magnetic Behavior

Magnetic Behavior

Magnetic Behavior After this reading this section you will be able to do the following: Perform an experiment to detect what materials are magnetic and explain why you think they are magnetic. Magnetism Just like when the Greeks of the old times discovered the first naturally occurring magnetic stones, or natural magnets, you have been [...]

  • List Of Ferromagnetic Metals

List Of Ferromagnetic Metals

List Of Ferromagnetic Metals Ferromagnetism, the ability of a substance to magnetize, is a property that depends on the chemical composition, crystalline structure, temperature and microscopic organization of the material. Metals and alloys are most likely to exhibit ferromagnetism, but even lithium gas has also been shown to be magnetic when cooled to less than [...]

A COMPREHENSIVE LIST OF FERROMAGNETIC MATERIALS

A COMPREHENSIVE LIST OF FERROMAGNETIC MATERIALS Metals and magnetism go hand in hand. Magnetism, whether it’s strong or weak, is a characteristic of metal along with conductivity, malleability, and ductility. But just as metals can be ductile but not malleable, or malleable but not ductile, magnetism isn’t a condition to be taken for granted. Metal [...]

What are the difficulties when cutting ferrite magnets?

What are the difficulties when cutting ferrite magnets? A ferrite magnet is a metal oxide having ferromagnetism. In terms of electrical characteristics, ferrite magnets have much higher electrical resistivity than metal and alloy magnetic materials, and also have higher dielectric functions. The magnetic function of the ferrite magnet also exhibits a high magnetic permeability at [...]
