ABSTRACT:
A method comprising the steps of: allowing the directions of a magnetic field, an electric current and the liquid metal flow to perpendicularly intersect to one another; and varying at least one of the magnetic field and the electric current in intensity in response to the temperature of the liquid metal. A force acting on the liquid metal flow is increased and decreased by the interaction between the magnetic field and the electric current. An apparatus for performing the method comprising material varying in electric property with the temperature of the liquid metal. The material is installed in at least one of a path of the magnetic field, a path of the electric current and means for generating the magnetic field. Variation of the electric property of the material allows one of the magnetic field and the electric current to be automatically increased or decreased in intensity in response to the temperature of the liquid metal, so that the force acting on the liquid metal flow is controlled.
