What is the susceptibility of a medium if its relative permeability is \(0.85 ?\)
- A 1.85
- B 0.15
- C -0.15
- D -0.85
Answer & Solution
Correct Answer
(C) -0.15
Step-by-step Solution
Detailed explanation
Relative permeability, \(\mu_{\mathrm{r}}=1+\mathrm{x}\)
\(\therefore \mathrm{x}=\mu_{\mathrm{r}}-1=0.85-1=-0.15\)
\(\therefore \mathrm{x}=\mu_{\mathrm{r}}-1=0.85-1=-0.15\)
