A method and apparatus for distributing power to a plurality of computers in a network. The circuit is capable, before selection of each line from said set of lines, of precharging at least the columns to be selected to a precharge voltage. In order to positively change the characteristic curve of the magnetic flux of the legs and teeth, the teeth continuously form an area overlap with the legs in the direction of rotation of the rotor in accordance with the angle of rotation.
