ガラス製水銀整流器に及ぼす磁界の影響
INFLUENCE OF MAGNETIC FIELD ON A MERCURY ARC RECTIFIER
小山, 恒夫
Many authors have experimented on influence of magnetic field on electrical discharge in mercury vapor at low pressure. This paper differ from that results, and deals with the influence of perpendicular magnetic field on arc discharge in mercury arc rectifier, and the main anode current is D. C. , the exciting current is A. C. According to this experiment, the anode current increase by the action of magnetic field than the non magnetic field at a certain limit. The main results are as follows. (1) Characteristics of starting and breaking anode current are different due to direction and intensity of magnetic field in a certain anode current. (2) In a certain anode current, magnetic field's direction, position and intensity, the anode current increase or the arc voltage decrease than its at H=O. And the characteristics of the each current for two anode are unsymmetry on the direction of field and shift about 30 degree from the symmetrical axis.(3)The phenomena were obtained on a hot cathode mercury vapor rectifier too. From the above experiment,the result are given in the figures 1to 6 inclusive.I consider that the reason in those terms are following items: the path of electron take the most short path due to magnetic field at limits,the material (graphite)of the anode are non homegeneous or a part of its surface is lower electrical resistance than the other parts. And the action of the magnetic field gives good efficiency to mercurry arc rectifier,and this method shall be able to find the homogeneity or not of the material.
