内容記述 | In order to examine the couplings between poloidal or toroidal magnetic fields of different type, magneto-hydrodynamic oscillations of a fluid sphere under the influence of a uniform magnetic field are studied. A set of simultaneous differential equations for the oscillation is obtained in a general form which contains harmonic constituents of successive degrees. Although the writer can not solve the equation rigorously, some features of the coupling are qualitatively examined. A simple normal mode of the free oscillation is also studied by taking into account only the S10 and S30 type magnetic fields. | |||||
