22.2: Ferromagnets and Electromagnets
Ferromagnets. Only certain materials, such as iron, cobalt, nickel, and gadolinium, exhibit strong magnetic effects. Such materials are called ferromagnetic, after the Latin word for iron, ferrum.A group of materials made from the alloys of the rare earth elements are also used as strong and permanent magnets; a popular one is neodymium.
Ferromagnetic domains (Chapter 7)
Ferromagnetic domains are small regions in ferromagnetic materials within which all the magnetic dipoles are aligned parallel to each other. When a ferromagnetic material is in its demagnetized state, the magnetization vectors in different domains have different orientations, and the total magnetization averages to zero.
