Carbon steel magnetic, mainly due to the presence of iron in it. Iron is a magnetic element, and when iron atoms are arranged to form a ferromagnetic region, they form a magnetic moment in that region and exhibit strong magnetism. Carbon steel is an alloy of iron and carbon, which has a high content of iron, and therefore carbon steel is also magnetic.
Yes, carbon steel rust when exposed to moisture and oxygen, as the iron content in carbon steel reacts with these elements to form iron oxide, commonly known as rust. However, rusting can be delayed or prevented through protective coatings, alloying, and regular maintenance.
