The flute instability at the inner edge of a thin diamagnetic accretion disk is analyzed. The
magnetic field configuration model fromAly (1980) is used. We have analyzed a modified dispersion relation
for the flute instability that takes into account the Keplerian disk rotation. We have derived the inner radius
of the accretion disk within our analysis of the flute instability.We show that the inner radius does not differ
from the Alfve´ n radius for spherical accretion to within a dimensionless coefficient, with the proportionality
coefficient depending only on the turbulence alpha parameter and the relative disk thickness (h/r).
