Magnetic saturation is the state reached when an increase in applied external
magnetic field cannot increase the
magnetization of the material further, so the total magnetic flux density more
or less levels off. (Though, magnetization continues to increase very slowly
with the field due to paramagnetism.) Saturation is a characteristic of
ferromagnetic and ferromagnetic materials, such as iron, nickel, cobalt and
their alloys. Different
ferromagnetic materials have different saturation levels.
Ferromagnetic materials magnetic saturation
Saturation is typically shown on magnetization curve (axis X shows magneetic
H-field in ampere turns per cm, while axis Y shows magnetic B-field in Tesla)
Magnetic Saturation of ferromagnetic materials in order of curve profiles is
sheet steel, cast steel, tungsten steel, magnet steel, cobalt and magnetite.
