Description/Abstract Numerical results are presented of the finite Larmor radius (FLR) treatment of the tilting mode as described by Seyler and Barnes. We have two principal results. First, the FLR theory of tilting has singularities at the magnetic axis that make application of the theory unphysical. Second, numerical results will be presented showing that for current experiments the magnetic moments of the ions are poorly conserved at the tips of the flux surfaces in an FRC, ad therefore there is a priori reason to view an FLR theory as suspect for global modes in FRCs.
