2. Ferromagnetism - Wikipedia

   en.wikipedia.org/wiki/Ferromagnetism

   Paramagnetism, ferromagnetism, and spin waves. Ferromagnetism is a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet.

3. Non-stick surface - Wikipedia

   en.wikipedia.org/wiki/Non-stick_surface

   Cast iron, carbon steel, [1] stainless steel [2] and cast aluminium cookware [citation needed] may be seasoned before cooking by applying a fat to the surface and heating it to polymerize it. This produces a dry, hard, smooth, hydrophobic coating, which is non-stick when food is cooked with a small amount of cooking oil or fat.

4. Magnetic alloy - Wikipedia

   en.wikipedia.org/wiki/Magnetic_alloy

   A magnetic alloy is a combination of various metals from the periodic table such as ferrite that exhibits magnetic properties such as ferromagnetism. Typically the alloy contains one of the three main magnetic elements (which appear on the Bethe-Slater curve ): iron (Fe) , nickel (Ni) , or cobalt (Co) .

5. Cast iron - Wikipedia

   en.wikipedia.org/wiki/Cast_iron

   Cast iron is made from pig iron, which is the product of melting iron ore in a blast furnace. Cast iron can be made directly from the molten pig iron or by re-melting pig iron, [4] often along with substantial quantities of iron, steel, limestone, carbon (coke) and taking various steps to remove undesirable contaminants.

6. Ferrite (magnet) - Wikipedia

   en.wikipedia.org/wiki/Ferrite_(magnet)

   Above 585 °C Fe(II)-Fe(III) 2 O 4 transforms into the non-magnetic gamma phase. [6] Fe(II)-Fe(III) 2 O 4 is commonly seen as the black iron(II) oxide coating the surface of cast-iron cookware). The other pattern is M·Fe(III) 2 O 3, where M is another metallic element.
