The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...

For years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon ...

Metals are the only substances that are magnetic. But some metals are magnetic and some are not. The most common magnetic metal is iron. You don't see too many objects made of pure iron but you do see ...
