Magnet manufacturer to introduce you to a permanent magnet

In general, in the absence of applied magnetic field, magnets can keep for a long time itself. Permanent magnets available ferromagnetic materials, such as iron, nickel, etc. The mineral content of molecular arrangement of general chaos, influence each other just don't show the magnetic magnetic area, but in the external force, such as magnetic field under the guidance of molecular orientation trend is consistent, just show magnetic, which is commonly known as the magnet, iron, cobalt, nickel, is the most commonly used permanent magnets and magnetic materials basically magnet soft iron, permanent magnet is strong magnetic combined to make the spin of magnetic materials and electronic angular momentum into fixed direction; Take out, such as soft magnetic is combined with current, current soft magnetic iron will slowly lost. That is about the introduction of a permanent magnet, want to learn more knowledge to welcome you all to come to consult. Our website is not miss oh!
