What are hard magnetic materials?

Hard Magnetic materials- They have a slowly rising magnetization curve along with large hysteresis loop area and therefore large energy losses. These materials have high value of retentivity and low permeability and high value of coercivity. To saturate the hard magnetic materials, a high magnetizing force is needed. Hard magnetic materials have property of storing a significant amount of magnetic energy after magnetization and retaining similar for a long time. Because of this property they are used in the manufacture of permanent magnets.
