Always keep permanent magnets magnetic reason

　　In many devices, the permanent magnets will spend. It allows these devices can play a greater role, it is permanently magnetic, and does not require users to give it power. Many users do not understand why the magnetic presence of permanent magnets can be permanent.

　　Permanent magnet is a permanent magnet products, raw materials, which is a stone with magnetic. It can give grace under natural conditions in a relatively stable state, for which it is able to maintain a permanent magnetic. This natural magnet consists of many tiny lattice compositions. The lattice has a very interesting feature because they can rotate about one axis and then the ring current. Each ring current are able to build into a small magnet. If it is large circular currents come together, they will build into a large magnetic force of the magnet.

　　Permanent magnet ring current is very large, and can be in a lower energy state in the natural environment. Since these small lattice is a stable state, so that their energy is the lowest. To this end, it will allow the ring current is always kept in a direction, the magnetic properties of the permanent magnet will not disappear. However, when the ring current direction within the crystal lattice is inconsistent, it will make permanent magnets lose their magnetism.
