Magneto-hydrodynamic Oscillations of a Conducting Liquid Mass Rotating in a Uniform Magnetic Field

抄録

Considering Magneto-hydrodynamic oscillations of an infinitely long cylinder of electrically conducting liquid medium rotating in a uniform magnetic field, we see that the periods of oscillations are much different from that of non-rotating cylinder, when Coriolis force is much larger than the electro-magnetic force.
We obtain two periods T₁, T₂ for one mode of oscillation
T₁>T₀>T₂
where T₀ is the period of non-rotating cylinder.
