Calculation of the ionization state and consequent magnetic Reynolds number for the solar nebula shows that the presence of26Al will result in strong coupling of the gas to magnetic fields. In the absence of26Al,40K will still result in substantial ionization, but the degree of magnetic coupling is much more model dependent.
