Question

Magnetic domains during the process of magnetization of ferromagnetic materials, rotate first and then expand

Answer 1

A ferromagnetic material is one that has magnetic properties similar to those of iron. In other words, you can make a magnet out of it. Some other ferromagnetic materials are nickel, cobalt, and alnico, an aluminum-nickel-cobalt alloy.

Magnetic fields come from currents. This is true even in ferromagnetic materials; their magnetic properties come from the motion of electrons in the atoms. Each electron has a spin. This is a quantum mechanical phenomenon that is difficult to make a comparison to, but can be thought of as similar to the rotation of the Earth about its axis.

Electron spins are in one of two states, up or down. This is another way of stating that the magnetic quantum number can be +1/2 or -1/2. Electrons are arranged in shells and orbitals in an atom. If they fill the orbitals so that there are more spins pointing up than down (or vice versa), each atom will act like a tiny magnet.

Answer 2

Answer:

A ferromagnetic material exists one that contains magnetic properties comparable to those of iron. In other words, you can create a magnet out of it. Some other ferromagnetic materials exist as nickel, cobalt, and alnico, an aluminum-nickel-cobalt alloy.

Explanation:

Magnetic fields reach from currents. This exists true even in ferromagnetic materials; their magnetic effects come from the motion of electrons in the atoms. Each electron contains a spin. This exists a quantum mechanical phenomenon that exists laborious to create a comparison to but can be considered equivalent to the process of the Earth about its axis.

Electron spins exist in one of two forms, up or down. This exists another method of noting that the magnetic quantum number can be +1/2 or -1/2. Electrons are organized in shells and orbitals in an atom. If they fill the orbitals so that there are more spins indicating up than down (or vice versa), the apiece atom will act as a small magnet.
