ABSTRACT:
Provided is an electro-sensitive movable fluid composition which is comprised of a compound or a mixture of compounds which, at the working temperature of the fluid, has a conductivity .sigma., plotted as abscissa, and a viscosity .eta., plotted as ordinate, the triangle having, as vertexes, a point P indicated by the conductivity .sigma.=4.times.10.sup.-10 S/m and the viscosity .eta.=1.times.10.sup.0 Pa.S, a point Q indicated by the conductivity .sigma.=4.times.10.sup.-10 S/m and the viscosity n=1.times.10.sup.-4 Pa.S, and a point R indicated by the conductivity .sigma.=5.times.10.sup.-6 S/m and the viscosity .eta.=1.times.10.sup.-4 Pa.S. Also provided is a method for driving a rotor by producing a jet flow of the electro-sensitive movable fluid upon application of direct-current-voltage between two electrodes immersed in the fluid.
