Saturation (magnetic)
open-in-new
<p>Seen in some <a href="/facts/Magnetism/eo75vApl">magnetic</a> materials, saturation is the state reached when an increase in applied external <a href="/facts/Magnetic_field/Ta8Ev588">magnetic field</a> <i>H</i> cannot increase the <a href="/facts/Magnetization/zxrtXzTN">magnetization</a> of the material further, so the total magnetic flux density <i>B</i> more or less levels off. (Though, magnetization continues to increase very slowly with the field due to <a href="/facts/Paramagnetism/vj1SMbbp">paramagnetism</a>.) Saturation is a characteristic of <a href="/facts/Ferromagnetism/fH3HFnSl">ferromagnetic</a> and <a href="/facts/Ferrimagnetism/sMcg7RYt">ferrimagnetic</a> materials, such as <a href="/facts/Iron/QK1JYy8E">iron</a>, <a href="/facts/Nickel/KwMCHYRP">nickel</a>, <a href="/facts/Cobalt/gqhScEw4">cobalt</a> and their alloys. Different ferromagnetic materials have different saturation levels. </p>
