Answer:
The main ferromagnetic metals are iron, nickel, and cobalt. The uncommon element gadolinium is magnetic. These form alloys that are also magnetic, such as steel. The rare-earth elements neodymium and samarium can also form magnetic alloys, and neodymium magnets are among the most powerful of permanent magnets.
*The element titanium is not ferromagnetic. It is paramagnetic, in that it interacts weakly with a magnetic field. Copper ions in solution also demonstrate paramagnetism.
*The elements silver, mercury, and gold can display diamagnetism, being slightly repelled by a strong magnetic field. Compounds of these elements can display very weak magnetic interactions. They will not display magnetic properties, but become increasingly affected at very low temperatures.
