Wecalculate the yield of high energy neutrinos produced in astrophysicalsources for arbitrary interaction depths tau₀ and magnetic field strengthsB. We take into account energy loss processes like synchrotronradiation and diffusion of charged particles in turbulent magnetic fieldsas well as the scattering of secondaries on background photonsand the direct production of charm neutrinos. Meson-photon interactions aresimulated with an extended version of the SOPHIA model. Diffusionleads to an increased path length before protons leave thesource of size R_s and therefore magnetized sources lose theirtransparency below the energy E~10¹⁸ eV(R_s/pc)(B/mG)tau₀^1/alpha, with alpha=1/3 and 1 forKolmogorov and Bohm diffusion, respectively. Moreover, the neutrino flux issuppressed above the energy where synchrotron energy losses become importantfor charged particles. As a consequence, the energy spectrum andthe flavor composition of neutrinos are strongly modified both atlow and high energies even for sources with tau₀<~1.
