  • Current streamline method for coil construction
    Patent number: 4840700
    Abstract: Etching methods are employed on a thin conducting sheet so as to fabricate complicated magnetic coil patterns which are necessary to produce magnetic fields of high uniformity or other given design. The etching is performed so that material is removed along a thin line or lines which correspond to current streamlines of the ideal current distribution so that the remaining material exhibits a relatively wide region of conducting material having reduced electrical resistance.
