The magnetic susceptibility of a material of a rod is 499 . Permeability in vacuum is \(4 \pi \times 10^{-7} \mathrm{H} / \mathrm{m}\). Absolute permeability of the material of the rod is:
(1) \(4 \pi \times 10^{-4} \mathrm{H} / \mathrm{m}\)
(2) \(2 \pi \times 10^{-4} \mathrm{H} / \mathrm{m}\)
(3) \(3 \pi \times 10^{-4} \mathrm{H} / \mathrm{m}\)
(4) \(\pi \times 10^{-4} \mathrm{H} / \mathrm{m}\)
