Susceptibility and retentivity
WebKey (1) Retentivity is defined as the intensity of magnetisation remaining in the substance when the magnetizing field has been reduced to zero. Hence key (1) is not correct. Key(2) Magnetic susceptibility is the ratio of magnetic moment to unit volume but it is not energy dissipation (loss) in cycle hence key(2) is not correct. http://hyperphysics.phy-astr.gsu.edu/hbase/Tables/magprop.html
