    Sorry in paramagnetic susceptibility is positive

    1Thank You

    Surbhi Raghu 7 years, 6 months ago

    Diamagnetic -: 1) magnetic field lines are expelled by these substances. 2) their permeability is negativeve. 3) Their susceptibility is also negative. 4) there is no effect of the temperature over the magnetic behaviour of these substances . Paramagnetic-: 1) magnetic field lines pass through them. 2) permeability is greater than 1. 3) susceptibility is negative. 4) at curie temperature they lose their magnetism. Ferromagnetic-: 1) permeability is very less than 1. 2) susceptibility is also very less than 1. 3) at curie temperature they convert into paramagnetic substances.
