Magnetic attraction and iron absorption principle is introduced _ ndfeb strong magnet manufacturers
Magnetic attraction and iron absorption principle is introduced many people focus on the principle of the magnet?
Asked why the magnet can attract the iron?
The principle is what?
Today Ricky magnet card manufacturers today is to talk with you.
Why can the magnet attracts iron?
Magnet iron absorption determined by the characteristics of the magnet, if the atom current explanation is that current magnetization of the magnetic field of another object, which produces an electric field magnetic objects interact to produce electric field force, namely the magnets will attract iron.
Magnet is the magnetization process of pig iron absorption process, the magnetized iron and magnet attraction between different polarity, iron and magnet is & other;
Sticky & throughout;
He said that he magnet magnetic.
Material is mostly made up of molecules, molecular is made of atoms, atoms are composed of atomic nuclei and electrons.
From inside the atom, the electronic constant rotation, and rotate around the nucleus.
These two movement produces magnetic electrons.
But in most materials, electronic movement in the direction of each are not identical, desultorily, magnetic cancel each other out.
Therefore, most material under normal circumstances, do not present magnetic.
Such as iron, cobalt, nickel or ferrite ferromagnetic kind material is different, its internal electron spin can spontaneously lined up in a small scope, forming a spontaneous magnetization, the spontaneous magnetization area is called magnetic domain.
Ferromagnetic kind material after magnetization, internal magnetic domain uniformly lined up neatly, direction, make the magnetic strengthen, constitute a magnet.
What is the cause magnet attraction?
The interaction force between the magnet is a very wonderful thing, so people also very keen on the study of them, it would not have been so they are widely used in society.
Each kind of knowledge to learn to learn thoroughly do need a long process, Ricky small make up and share about the principle of magnets attract each other.
AB magnets attract and attraction between atoms is A truth, that is A magnet of some atoms and B magnet combining some of the atoms.
Important: in the process of the magnet and magnet near releases heat,
Energy and particles)
, namely the combination of atoms and atomic to release energy, in daily life we don't feel that feeling don't own a negative energy balance.
Analysis: an independent principle of magnet, the magnet from a regular rotary spherical particles with each step is outside the role of the particle, after a difficult movement process, out of a curve track, the movement to the other side into the reverse rotating sphere.
A very important: if the particle in the process of movement, the speed of the same size, the particle movement in the direction of change, the greater the joint force of particles by the outside world, the greater the joint force of 0 if the particle a straight line, the curve movement of the particles, the greater the bending, the greater the force.
Analysis: the magnet and magnet B meet, A magnet B correct rotary spherical particles directly into the magnet from A reverse rotating sphere, meaning that these particles are no longer experience difficult movement process, reduced the bent at the ends of the line, the outside force decreased A lot.
Why do magnets attract each other?
Magnets are attracted to each other, is because has the ferroelectricity (
A related to metal ion in the structure of nature)
, this is the knowledge of the material physical properties and more deep, aluminum, copper and so on do not have this kind of performance, so don't be attracted.
Stainless steel is to join the elements such as chromium ferroalloy, destruction of the composition of the metal cation was because magazine, make its loss of ferroelectricity, also will not be attracted.
