    • Ferromagnetism occurs when individual atoms are paramagnetic and the spin vectors are aligned parallel to each other in a crystalline material.
    • Metallic iron is an example of a ferromagnetic material involving a transition metal.
    • Anti-ferromagnetism is another example of a magnetic property arising from a particular alignment of individual spins in the solid state.
    • Ferromagnetism is the physical theory which explains how materials become magnets.
  • Transition Metals

    • Ferromagnetism occurs when individual atoms are paramagnetic and the spin vectors are aligned parallel to each other in a crystalline material.
    • Metallic iron and the alloy alnico are examples of ferromagnetic materials involving transition metals.
