Magnets attract iron due to the influence of their magnetic field upon the iron. Before a piece of iron enters the magnetic field of a magnet, the polarization of the iron s atoms is random.

The popular understanding of a magnetic material is ferromagnetism, such as in iron, Fe. Most metals with magnetic properties are ferrous: metals and alloys that contain iron. These ferrous metals include mild steel, carbon steel, stainless steel, cast iron, and wrought iron. Two materials found in nature, lodestone (or magnetite, an oxide of iron, Fe 3 O 4) and iron, have the ability to acquire such attractive powers, and they are often called natural ferromagnets. They were discovered more than 2,000 years ago, and all early scientific studies of magnetism were conducted on these materials. Electromagnets are made from a coil of copper wire wound around a core made from iron, nickel or cobalt.

Magnets attract iron, and because of this, they are utilized in various forms. There are a lot of magnets that we can see in our daily lives as well — like the tiny magnets on souvenir magnets that stick on the fridge door, magnetic snaps that help items close tightly, and so on.

different particle size distributions and particle morphology. Examples: ASC 100.29 is a pure iron powder for cost-effective sintered soft magnetic components.

These are also called permanent magnets because they always retain a certain degree of their magnetism.

The word actually means iron-magnetism because that is the most familiar example of the phenomenon and the one scientists first studied. The reason for iron’s strong magnetic field also depends on magnetic susceptibility. It is the degree to which a material can be magnetized in an external magnetic field. This increases with increasing temperature due to the parallel alignment of dipoles towards the direction of the field. Iron is magnetic except when heated to the Curie point. The Curie point, which is sometimes called the Curie Temperature, is the temperature at which some magnetic materials undergo a major change in their structure.

The other magnetic elements include cobalt andnickel.

Magnets steels, which are now largely obsolete, have been replaced in the most part by ternary alloys of iron, cobalt, and molybdenum, or tungsten.

Magnets Reveal Hidden Cereal Ingredient! Many cereals are fortified with added iron, one of many necessary vitamins and minerals. These items are added to the mix when the cereal is are made, so it is a bit like taking your vitamin with the cereal. Since iron is attracted to magnets, finding it can be an instructive science experiment.

The reason these three metals are so strongly magnetic is not completely understood. Their outer-most electrons tend to possess spins that line-up. This alignment, whatever the reason, is what gives cobalt, iron and nickel their very strong magnetic properties compared to most other materials. Iron is a grey, silvery metal. It is magnetic, though different allotropes of iron have different magnetic qualities.
