We calculate the radiation spectra from advection-dominated accretion flows(ADAFs), taking into account the effects of a global magnetic field.Calculation is based on the analytic model for magnetized ADAFs proposed byKaburaki, where a large-scale magnetic field controls the accretion process.Adjusting a few parameters, we find that our model can well reproduce theobserved spectrum of Sagittarius A$^{*}$. The result is discussed in comparisonwith those of well-known ADAF models, where the turbulent viscosity controlsthe accretion process.Comment: Accepted for publication in Ap
