This invention relates to the field of magnetic apparatus, especially as such apparatus is employed to generate relatively long uniform magnetic fields for devices such as an electrical signal delay line. A laminar magnetic flux generating apparatus for use with a signal delay line or other apparatus requiring a long, narrow, uniform field. Magnetic flux orthogonal to the primary flux is generated by an array of spaced apart magnets located along the length of the long, narrow, uniform field combined orthogonal and primary fluxes provide the desired long, narrow, uniform field flux within a magnetically conductive enclosure. Vector summation and fluid analogies for the achieved flux are disclosed.
