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 \[{{\mu }_{r}}\] is greater than 1 and susceptibility has always positive value. Hence \[\chi >0\]
