\(\mu_0\) is permeability of vacuum, \(\chi_m\) is susceptibility then permeability of material is _________.
- A \(\mu=\mu_0 1+\chi_m\)
- B \(\mu=\mu_0\left(\chi_m-1\right)\)
- C \(\mu=\mu_0\left(1-\chi_{ m }\right)\)
- D \(\mu=\mu_0\left(1+\chi_m\right)\)
Answer & Solution
Correct Answer
(D) \(\mu=\mu_0\left(1+\chi_m\right)\)
Step-by-step Solution
Detailed explanation
D
from \(\mu_r=\frac{\mu}{\mu_0}=\left(1+\chi_m\right)\)
from \(\mu_r=\frac{\mu}{\mu_0}=\left(1+\chi_m\right)\)
