Because of its magnetic properties, nickel is also part of Alnico magnets (made of aluminium, nickel, and cobalt). These magnets are stronger than rareearth metal magnets but weaker than ironbased magnets. Cobalt. Cobalt is an important ferromagnetic metal. For over 100 years, cobalt''s excellent magnetic properties have helped develop a variety of applications.

Magnetic Saturation Seen in some magnetic materials, saturation is the state reached when an increase in applied external magnetizing field H cannot increase the magnetization of the material further, so the total magnetic field B levels off. It is a characteristic particularly of ferromagnetic materials, such as iron, nickel, cobalt and their ...
