The magnetic susceptibility of the material of a rod is 499. Permeability of vaccum is \(4 \pi \times 10^{-7} \mathrm{H} / \mathrm{m}\). Absolute permeability of the material of the rod in \(\mathrm{H} / \mathrm{m}\) is:
- A \(\pi \times 10^{-4}\)
- B \(2 \pi \times 10^{-4}\)
- C \(3 \pi \times 10^{-4}\)
- D \(4 \pi 10^{-4}\)
Answer & Solution
Correct Answer
(B) \(2 \pi \times 10^{-4}\)
Step-by-step Solution
Detailed explanation
Magnetic susceptibility, \(\chi=499\) \(\mu_0=4 \pi \times 10^{-7} \mathrm{H} / \mathrm{m}\) Relative permeability of the rod, \(\mu_r=1+\chi=1+499=500\) Absolute permeability, \(\mu=\mu_r \mu_0\) \(=500 \times 4 \pi \times 10^{-7}\) \(=20 \pi \times 10^{-5}\)…
