The initial results obtained are as follows : (1) The eigenperiod of the localized toroidal (shear Alfven mode) oscillation is effectively controlled by the height-integrated Hall conductivity. (2) A global monochromatic toroidal oscillation is excited by the fast magnetosonic wave via the ionospheric induction current.}, pages = {49--59}, title = {Effect of the ionospheric induction current on magnetohydrodynamic waves in the magnetosphere}, volume = {8}, year = {1995} }
