What Metals Do Magnets Stick To?
Metals that naturally attract magnets are known as ferromagnetic metals; these magnets will firmly stick to these metals. For example, iron, cobalt, steel, nickel, manganese, gadolinium, and lodestone are all ferromagnetic metals. Some metals, including iron, are referred to as magnetically soft because they become strong temporary …

Iron
Iron is the third most common element making up the Earth. Iron is one of the three naturally magnetic elements; the others are cobalt and nickel. Iron is the most magnetic of the three. The principle ores of iron are hematite (70% iron) and magnetite (72% iron). Taconite is a low-grade iron ore, containing up to 30% magnetite and hematite.

Is Cast Iron Magnetic or Non-magnetic?
These metals include stainless steel, mild steel, carbon steel, wrought iron, and cast iron. Therefore, it is safe to say that a cast iron pan should be magnetic. Note, though, that not every cast iron is as magnetic as the next. Some factors affect how magnetic it is, namely: Purity of the Iron. Type of Magnet Used.

Is Stainless Steel Magnetic? | Eclipse Magnetics
Ferritic stainless steels - these steels are magnetic primarily due to the presence of ferrite, a compound of iron and other elements. The crystals of ferrite and iron make this type of stainless steel magnetic. It is also important to note that some stainless steels with ferrite have a weak magnetic pull. Stainless steel grades 409, 430, and ...

Does blood have magnetic properties? — Science Learning Hub
A magnetic field occurs around a magnetised object. It can attract or repel other magnetic objects. You can see this field if you place iron filings around a magnet. The earth also has a magnetic field, which is caused by electrical currents within the earth. The strength of a magnetic field is measured in teslas (T).

Some Meteorites Are Mysteriously Magnetic, And We
Magnetic meteorites occur because they form in the presence of a magnetic field. The iron grains within the meteorite are aligned along the external magnetic field, which gives the meteorite its own magnetism. For example, the Martian meteorite known as Black Beauty gained its magnetism from the strong magnetic field of young Mars.

Is Cast Iron Magnetic? [Technically, Yes, But…]
Being magnetic and being a magnet isn't the same thing. Cast iron, for instance, is magnetic, but it's different from a magnet itself. A magnet is an alloy or material that is composed of atoms ordered so that the material becomes magnetic. This makes it attracted to other magnets or a magnetic field.

Rusty Metal and Magnetism | Physics Van | UIUC
Rust and corrosion strongly affect the magnetic properties of metals. Ferromagnetic metals like iron in which interactions between the electrons of neighboring atoms tend to make their little bits of magnetism point in the same direction, forming magnetic domains. In a magnetic field, these domains line up with the field making a strong magnet.
