Abstract
This paper investigates on the performance of liquid magnetic compass measuring the concomitant angle of the directional system by the kind of compass and the coefficiant of viscosity of the liquid of ones in accordance with the turning angular velocity of the compass bowl in artificial horizontal magnetic fields. The obtained results are as follows; 1. The concomitant angle is to be in proportion to the coefficiant of viscosity of the liquid of compass and the turning angular velocity of the compass bowl, but ones is to be in contrary proportion to the magnetic moment of the magnetic needle and the horizontal geomagnetic. 2. The overdevelopment of the concomitant angle keeps on regularly at any optional degree in the turning angular velocity over
