they are iron nickel cobalt and manganese
Iron (or, from a physics standpoint, ferrous or, more probably, ferromagnetic metal). Magnets attract magnetic material, and there are only a few ferrous materials around. The word ferrous is from the word ferrum, which is the Latin word for iron. The chemical symbol for iron is Fe and it comes from the same source. Iron, cobalt and nickel are the "big three" ferromagnetic materials, but gadolinium and dysprosium also exhibit ferromagnetic properties. Certainly compounds and mixtures that include these elements are (usually) ferromagnetic. Wikipedia has some good info posted in their article on ferromagnetism. Need a link? You got it.

A bill of materials is a list of materials and components used in a manufactured item, which are sometimes appended to an engineering diagram of the item.
A Material Takeoff is the process of analyzing(this includes list of materials with quantities and types,grades of materials and the weights of such materials) drawings and determining all the materials required to complete the design. A Bill of Materials is adocument that shows detailed desgriptions of materials used in completing a project,this includes,types of materials,specification of each item,gost of each item used,number and cost of labour used in completing the poject. The major difference between the two is:MTO is needed to make a BOM,a BOM aids in the procurement and requisition of materials.
That would be an impermiable materials.
The three methods of magnetization are: ferromagnetism, paramagnetism, and diamagnetism. Ferromagnetism occurs in materials like iron and nickel, where the magnetic moments of atoms align spontaneously. Paramagnetism arises in materials with unpaired electrons that are attracted to an external magnetic field. Diamagnetism is a weaker form of magnetism exhibited by all materials, where electron motion generates a weak opposing magnetic field.

Ferromagnetism occurs when the magnetic moments of atoms align in the same direction, creating a strong magnetic field. The alignment is maintained even after the external magnetic field is removed due to interactions between adjacent atoms. This phenomenon is responsible for the permanent magnetism observed in materials like iron, cobalt, and nickel.
I believe those would basically be the ferromagnetic materials. You can find a list of elements and compounds here: http://en.wikipedia.org/wiki/Ferromagnetism#Ferromagnetic_materials See the table on the right.
Cobalt, iron, and nickel exhibit ferromagnetism at reasonable temperatures. Check the Wikipedia article on "ferromagnetism", for additional materials that exhibit ferromagnetism - some of them are compounds, and some only exhibit ferromagnetism at temperatures that are too low for many practical uses (for example, Dysprosium requires a temperature below 88 kelvin).

Paramagnetism refers to materials like aluminum or platinum which become magnetized in a magnetic field but their magnetism disappears when the field is removed. Ferromagnetism refers to materials (such as iron and nickel) that can retain their magnetic properties when the magnetic field is removed and kifjkjf
Ferromagnetism arises from the alignment of magnetic moments in a material, typically due to interactions between neighboring atoms. In liquids and gases, the lack of fixed atomic positions and close interactions between atoms prevent the alignment of magnetic moments required for ferromagnetism. As a result, these states of matter do not exhibit the same magnetic properties as solid materials with a fixed crystal lattice structure.
It is called the magnetic force. This is a force caused by the attraction or repulsion of the magnetic fields of the materials.
