Note: 3D printed spheroid for uniform magnetic field generation

This article is focused on a novel and practical production method for a uniformmagnetic field generator. The method involves building of asurfacecoil template using a desktop3D printer and winding of a conducting wire onto thestructure usingsurface grooves as a guide. Groove pattern was based on the parametric spheroidal helicalcoil formula. Thecoil was driven by a current source and themagnetic field inside wasmeasured using a Hall probe placed into the holes on the printedstructure. Themeasurements are found to be in good agreement with ourfinite element analysis results and indicate a fairly uniform field inside.
