Explain paramagnetism with suitable example .

Answer» Paramagnetic Substances : If the magnetic lines of forces are drawn into the substance the field (B) in the substances is greater than the applied(H) i.e. , `B gt H` . Such a substance is called paramagnetic substance . Paramagnetic substance moves from a weaker part of the field to a stronger part of the field . Paramagnetic substances are weakly attracted in a external Magnetic field . They exhibit paramagnetism due to the presence of unpaired electrons .
E.g. : `Cr^(+3) , Sc^(+2) , K_(3) [Fe(CN)_(6)]` .
