Distinguish between diamagnetic, paramagnetic and ferromagnetic substances on the basis of intensity of magnetization, magnetic susceptibility and permeability.

Intensity of magnetisation:-It represent the extend to which a material is magnetised Paramagnetic : They have tendency to move from a region of weak magnetic field to strong magnetic field .weakly attractedDiamagnetic : They have tendency to move from strong to weak field.weakly repelled.Ferromagnetic: Strong tendency to move from region of weak magnetic field to strong magnetic field. Strongly attracted.Susceptibility:Concept (How easily we can convert a magnetic substance into a magnet)Diamagnetic: Small and negativParagnetic: Small and slightly positiveFerromagnetic: High and highly positivePermeability:Concept: (it is the capacity of a magnetic substance to allow the aPassage of magnetic field lines through it )Paramagnetic; Greater than 1Diamagnetic: Less than 1Ferro magnetic: >>1
