Abstract
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.
