How is magnet made ?
In: 0
Metals (iron ores) when heated can cool with all of their electrons pointed in the same direction (is in the presence of another magnet. This is why meteors are sometimes magnetic (they get really hot when they enter our atmosphere) . We can do this in a factory, by heating iron and exposing it to a magnetic feild as it cools. (Also interesting, iron that is hot enough to glow brightly is not magnetic! [Curie point] Smith’s check the temperature by trying to stick a magnet to their metals, at certain stages to see if its the proper temperature to forge).
