A magnetohydrodynamic generator directly extracts electric power from moving hot gases through a magnetic field, without the use of rotating electromagnetic machinery. MHD generators were originally developed because the output of a plasma MHD generator is a flame, well able to heat the boilers of a steam power plant .
We consider the rotation of the cylinder when subjected to a rotating electric field (electrorotation) and the orientation of the cylinder in an AC field with constant direction (electro-orientation).

The electric field of an infinite cylindrical conductor with a uniform linear charge density can be obtained by using Gauss' law.Considering a Gaussian surface in the form of a cylinder at radius r > R, the electric field has the same magnitude at every point of the cylinder and is directed outward.The electric flux is then just the electric field times the area of the cylinder.

This finite value of induced magnetic field on the outer cylindrical wall has no doubt suggested that there exists an induced electric current within the solid outer cylinder. Because the outer cylinder is perfectly conductive, part of the electric current induced by the MHD flow will be able to bypass through the outer cylinder.
Induced Electric Fields. You must understand how a changing magnetic flux induces an electric field, and be able to calculate induced electric fields. Eddy Currents. You must understand how induced electric fields give rise to circulating currents called "eddy currents." Displacement Current and Maxwell's Equations.
