A general principle of the direct analogue simulation of static field components was searched for. As an application of this method, the simulation of the field of a semi-infinite solid solenoid was investigated. The results obtained show that, for several special static systems, it is able to accomplish direct simulations and it has considerable advantages. The simulating solution of the above cited solenoid was given by Bz and ψ curves. With these graphs, the solution of the distribution of field strengths and force lines of any solenoid can be facilitated.
