On the Behavior of the Triode Valve Under the Influence of Magnetic Field

Abstract

The triode valve in which the filament and the plate constitute coaxial cylinders was chosen and the magnetic force parallel to the filament was applied. The static chracteristics were greatly modified and maximum of the plate current were obserbed. The grid current becomes the maximum when the magnetic force is intermediate between the critical magnetic forces for the grid and the plate. The theoritical explanation and an example of application of the phenomena are given in this paper. (July 1924)
