(a) At a distance from an emitting antenna where the electric field has a maximum magnitude of \(15 \mathrm{~V} / \mathrm{m}\) when the air is dry, what is the maximum magnetic field magnitude?

(b) How does the value of \(E_{\max }\) change when the air is very damp, increasing the dielectric constant of the air?

(c) How does the value of \(B_{\max }\) change in the damp air? Assume that the antenna's potential difference is unaffected by the damp air.
