Cobalt, iron, and nickel are known as the iron triad.
No, iron,cobalt,and nickel are the only known magnetic substance.
magnetic alignment
The most common magnetic element that corrodes to form rust is iron. When aligned, atoms of iron will possess a magnetic field that will lead to interaction with other magnetic, ferrous materials. Iron will oxidize to form rust.
it is known as a magnetic domian.
Cast iron is magnetic because it is made up of iron atoms. Iron atoms are magnetic because they have unpaired electrons in their outermost shell.
Cobalt, iron, and nickel are known as the iron triad.
Without magnetic domains a magnet wouldn't have its magnetism. Magnetic domains are clusters of iron atoms that line up in the smae direction when magnetised. When unmagnitized the iron atoms scatter.
Domains
Iron nail is magnetic because it is made up of the element iron. The structure of an iron atom exhibit a unique magnetic behavior which is called ferromagnetism.

If the iron atoms are aligned then the object is magnetic, if they are randomly oriented then it is not. How the object was manufactured may be the cause of the difference, but it always possible to intentionally either magnetize OR demagnetize an object.
The magnet, in this case, will induce magnetism in the iron. The iron has lots of tiny areas that are magnetic, but normally point in random directions; placing a magnet nearby will allign those, and thus induce the magnetism.
The atoms in an iron are arranged in way were they are not able to slide, there are bigger and smaller atoms. This makes the iron hard.
