(The letters are explained in the text.) Next, the units are joined together so that each sends its output to the other three; and thereby each receives an input from each of the other three. These inputs act on the unit's magnet through the coils A, B, and C, so that the torque on the magnet is approximately proportional to the algebraic sum of the currents in A, B, and C. (D also affects M as a self-feedback.) But before each input current reaches its coil, it passes through a commutator (X), which determines the polarity of entry to the coil, and through a potentiometer (P), which determines what fraction of the input shall reach the coil. As soon as the system is switched on, the magnets are moved by the currents from the other units, but these movements change the currents, which modify the movements, and so on. It may be shown (S. 19/11) that if there is sufficient viscosity in the troughs, the four-variable system of the magnet-positions is approximately state-determined. To this system the com- mutators and potentiometers act as parameters. When these parameters are given a definite set of values, the magnets show some definite pattern of behaviour; for the para- meters determine the field, and thus the lines of behaviour. If 102.
