Characteristic strains using Equation (17) for WDs like WD1+B_P (﹩{B}_{\max }^{\mathrm{Toroidal}}=4\times 1{0}^{13}﹩ G, ﹩{B}_{p}^{\mathrm{Poloidal}}=8\times 1{0}^{8}﹩ G, initial ν = 0.05 Hz and initial χ = 3^∘, d = 1 kpc) at young (t ∼ 0) and old (near the end of the active timescale, t = 10⁵ yr) ages are shown along with detector sensitivities.
