What is a magnetic domain?

Answer 1

A magnetic domain is an atom or group of atoms within a material that have some kind of "net" or uniform electron motion. Let's look a bit more closely to see what that means and what the implications are.

A fundamental property of any charged particle is that when it is in motion, it creates a magnetic field around its path of travel. Electrons are negatively charged particles, and they create electromagnetic fields about themselves as they move. We know that electrons orbit atomic nuclei, and they create magnetic fields while doing so. Let's keep going from there.

If we take one or more atoms or groups of atoms and align them so that they have some kind of uniform electron motion, an overall magnetic field will be present in this region of the material. The individual magnetic fields of some electrons will be added together. The uniform motion of the electrons about atoms in this area creates a magnetic domain. In "regular" iron, these magnetic domains are randomly arranged. But if we align a large enough group of these magnetic domains, we'll have created a magnet.

Answer 2

Magnetic domains are found in ferromagnetic material. It could be an iron or steel bar, or in a permanent magnet. The magnetic domains are there, and they may be aligned or not.

The difference between the two examples is that in an iron or steel bar, the magnetic domains are randomly arranged. There is no net or overall magnetic field around the bar. In a magnet, many of the magnetic domains are aligned. The alignment of the magnetic domains creates an overall net magnetic field, and this piece of ferromagnetic material is now a permanent magnet.

Answer 3

An attractive area is district in which the attractive fields of iotas are assembled together and adjusted. In the examination underneath, the attractive areas are demonstrated by the bolts in the metal material. You can consider attractive spaces as smaller than normal magnets inside of a material.

The north-looking for post of such a magnet, or any comparative shaft, is known as a north attractive shaft. The south-looking for post, or any shaft like it, is known as a south attractive shaft. Not at all like posts of diverse magnets pull in one another, like shafts repulse one another.
