text: Some ceramics, such as barium ferrite or nickel zinc ferrites, are magnetic materials that provide stronger magnetic fields, weigh less, and cost less than metal magnets.
text: Most ceramics are also nonmagnetic materials, although ferrites (iron-based ceramics) happen to make great magnets (because of their iron content).
