The Hall effect multiplier has a Hall generator which is placed in an air gap of the exciting magneticcircuit. The multiplier output is given as a voltage proportional to the multiplication of Hall current andexciting current. Described in this article are the properties of Hall effect multiplier such as geometry, internal resistance, gain and accuracy of multiplication and temperature variation of output voltage. Themultiplier is in such design as to be applied to watt-onverter, multiplier/divider, square-oot computer, etc. of this multiplier, there are three types, one using the ferrite pot magnetic cores and the other twousing the laminated permalloy cores which are punched in EI shape. Each multiplier has a Hall generatormade of germanium cristal. In this germanium, the antimony is doped in optimum concentration so thatthe best multiplication gain and temperature characteristics are obtained. As an application of this Hall multiplier, the characteristics of watt-onverter is given in appendix.
