text: Some important properties used to compare permanent magnets are: remanence (B r ), which measures the strength of the magnetic field; coercivity (H ci ), the material's resistance to becoming demagnetized; energy product (B·H max ), the density of magnetic energy; and Curie temperature (T C ), the temperature at which the material loses its magnetism.
