Perpendicularly superposed magnetic fields

THE CHARACTERISTICS of a ferromagnetic reactor as a function of two perpendicularly superimposed magnetic fields were discussed in an article by Beck and Kelly¹ in 1948. The core and coil configuration shown in Fig. 1 illustrates one practical method for superposing two perpendicular magnetic fields. The core is a hollow toroid of ferrite material which encloses an annular coil, and which is wound toroidally by a second coil. This core and coil configuration will be referred to as a cross-field reactor.
