The authors have designed and tested an electromagnet planar microwiggler for use in free electron lasers (FEL's), constructed of current conductors wound on ferromagnetic cores. A prototype with a period of 1 cm and gap of 0.5 cm produced a peak field on axis in excess of 4.6 kG, with a linear {ital B/H} characteristic to about 3.2 kG. The field of each half-period of the wiggler is independently tunable by adjusting the current delivered to each, thus allowing for precision tuning and/or wiggler tapering. The authors employ general scaling laws to predict the performance of a geometrically similar design with a period of 5 mm.
