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

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 Domain Dynamics Along the Magnetic Hysteresis Curve Inside Permanent Magnet

Magnetic Domain Dynamics Along the Magnetic Hysteresis Curve Inside Permanent Magnet In the long history of permanent magnet research for more than 100 years, three-dimensional magnetic microscopy has been eagerly awaited to elucidate the origin of the magnetic hysteresis of permanent magnets. In this study, we succeeded in observing the three-dimensional magnetic domain structure of [...]

  • Why can some materials be turned into magnets It’s all thanks to magnetic domains

Why can some materials be turned into magnets? It’s all thanks to magnetic domains

Why can some materials be turned into magnets? It’s all thanks to magnetic domains In ferromagnetic materials, like iron and nickel, groups of atoms band together in areas called domains. The magnetic strength and orientation, also called the magnetic moments, of the individual atoms in such a domain are aligned with one another and all [...]

  • Magnetic Domains & Hysteresis

Magnetic Domains & Hysteresis

Magnetic Domains & Hysteresis Magnetic  Domains We know magnets aren’t attracted to everything; if we put a magnet on a wooden wall, it will fall right down. Generally, magnets are attracted to objects that are made of the metals iron, nickel, or cobalt. These materials are called ferromagnetic materials. The reason magnets stick to these [...]

  • Effects of metallic magnetic domains based on scanning electron microscope photos

What are Magnetic Domains?

What are Magnetic Domains? According to the properties of substances in an external magnetic field, substances can be divided into five categories: paramagnetic substances, diamagnetic substances, ferromagnetic substances, ferrimagnetic substances and antiferromagnetic substances. A ferromagnetic substance is a substance that is magnetized under the action of an external magnetic field and can maintain its magnetized [...]
