A) \[{{\varepsilon }_{r}} = 0.5, \,{{\mu }_{r}} = 1.5\]
B) \[{{\varepsilon }_{r}} = 1.5, \,{{\mu }_{r}} = 0.5\]
C) \[{{\varepsilon }_{r}} = 0.5, \,{{\mu }_{r}} = 0.5\]
D) \[{{\varepsilon }_{r}} = 1.5, \,{{\mu }_{r}} = 1.5\]
Correct Answer: B
Solution :
For diamagnetic material \[0 <{{\mu }_{n}} <1\] and for any material \[{{\varepsilon }_{n}}>1\] So, [b] is correct.
