list of ferromagnetic metals | sciencing

ferromagnetism the ability of a substance to magnetize is a property that depends on the chemical composition crystalline structure temperature and microscopic organization of the material. metals and alloys are most likely to exhibit ferromagnetism but even lithium gas has also been shown to be magnetic when cooled to less than one kelvin.

monel

monel is an alloy (i.e. combination of two or more elements of which at least one is a metal and where the resultant material has metallic properties). it is based on nickel (65-70%) and copper (20-29%) and also contains iron and manganese (5%) and other compounds.. monel was discovered by robert crooks stanley who worked for the international nickel company (inco) in 1901.

ferromagnetism | physics | britannica

ferromagnetism is a kind of magnetism that is associated with iron cobalt nickel and some alloys or compounds containing one or more of these elements. it also occurs in gadolinium and a few other rare-earth elements. in contrast to other substances ferromagnetic materials are magnetized easily and in strong magnetic fields the magnetization approaches a definite limit called saturation.
