The local stability of the Tokamak is discussed and a general approximate criteria β c obtained, where η is the longitudinal magneticwell. Furthermore, the influence of multipole' fields on the longitudinal magnetic well and the magnetic shear is discuss. It is observed that small triangular and octopole field components may considerably stabilize a Tokamak of elliptical cross-section.
