Why the ferromagnetic material can be attracted by strong magnet?
We can know the magnet iron goods such as adsorption, so why ferromagnetic material can be attracted by strong magnet?
Today by magnet factory small make up for everyone explanation: strong ferromagnetic material can be magnet attracted the fundamental reason is that it is the internal structure of the magnetic domain can be polarized magnetic field, after being polarized materials will be guided by a magnetic field.
Instead if material in the domain can not be magnetic polarization or difficult, it's a pity that the magnetic field of this kind of material is very weak, the action of the concrete's feature is each tube, not those who are attracted to feeling!
