    The relative permeability is represented by \[{{\mu }_{r}}\]and the susceptibility is denoted by \[\chi \]for a magnetic substance. Then for a paramagnetic substance:

    A)  \[{{\mu }_{r}}<1,\chi <0\]           

    B) \[{{\mu }_{r}}<1,\chi >0\]

    C)  \[{{\mu }_{r}}>1,\chi <0\]           

    D)  \[{{\mu }_{r}}>1,\chi >0\]

    Correct Answer: D

    Solution :

    It is clear that for a paramagnetic substance relative permeability \[{{\mu }_{r}}\] greater than 1 and susceptibility has always positive value. Hence \[\chi >0\]
