An electromagnetic approach is applied to unstable modes in the ion branch for a model helical geometry. Such pure kinetic effects as the stabilization of high‐n ballooning modes due to finite Larmor radius, and the suppression of ion temperature gradient modes, when the plasma‐ β is increased, are studied and new results from comparing these effects in twodimensional (i.e. tokamak) and three‐dimensional (i.e. model helical) geometry are reported.
