WhatsApp: +86 18221755073Magnets are made by exposing objects that contain nickel, iron, or cobalt to a magnetic field. When this happens, the structure of the material is actually changed on a microscopic level – the molecules of the object are polarized, or rearranged, into lines. When enough of the metal is polarized, it becomes a magnet.
