China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Magnets, some people may be in frequent contact with it, understand a little more, some people may not know, it is necessary to magnetize to have magnetic properties.
No magnetization of the magnet has no magnetic force is why?
The main reason is because the magnet is actually inside it is made up of countless very small magnetic powder combination, each one of the small magnetic powder between the magnetic force, but each other NS collection of mutual magnetic force to neutralize, and so on after the magnetization, these countless small particles are all lined up in a direction to the outside will show magnetic.
The pictures below show round magnets with countersunk holes, usually thickness magnetized and sometimes need to be used in pairs.
So the magnet is very concerned about the unity of a material, and to the permanent magnet magnet is actually a very important part, if the magnetization of your magnetic field is not strong enough, then in fact to the magnet is not saturated, that is to say, this bucket of water you did not give it full, the magnetic energy is actually a waste, then the next time you recharge when you have to pay a higher magnetic field, in order to put the rest of the part of it is full. There is only one way to verify if the magnetization is saturated or not, and that is to put the permanent magnet inside a larger magnetic field and see if the magnetic force increases.
The above is about whether the magnet is not magnetized magnetic introduction, belongs to the basic knowledge of magnets, to learn more about magnet knowledge welcome to pay attention to this website.
