The magnetic susceptibility of a material of a rod is 499. Permeability of vacuum is \(4 \pi \times 10^{-7} \mathrm{H} / \mathrm{m}\). Absolute permeability of the material of the rod in henry per meter is (A) \(\pi \times 10^{-4}\) (B) \(2 \pi \times 10^{-4}\) (C) \(3 \pi \times 10^{-4}\) (D) \(4 \pi \times 10^{-4}\)

Short Answer

Expert verified
The short answer is: The absolute permeability of the rod material is (B) \(2 \pi \times 10^{-4} \mathrm{H} / \mathrm{m}\).

Step by step solution

01

Identify given values and formula

We are given: Magnetic susceptibility (\(\chi_m\)) = 499 Permeability of vacuum (\(\mu_0\)) = \(4 \pi \times 10^{-7} \mathrm{H} / \mathrm{m}\) We need to use the formula: \(\mu_{\text{material}} = \mu_0(1 + \chi_m)\)
02

Plug in the given values into the formula

Substitute the given values into the formula: \(\mu_{\text{material}} = (4 \pi \times 10^{-7})(1 + 499)\)
03

Calculate the absolute permeability

Simplify the equation: \(\mu_{\text{material}} = (4 \pi \times 10^{-7})(500)\) \(\mu_{\text{material}} = 2 \pi \times 10^{-4}\)
04

Compare the result to the given options

We can now see that our result matches option (B): \(\mu_{\text{material}} = 2 \pi \times 10^{-4}\) So, the correct answer is (B) \(2 \pi \times 10^{-4}\).
