Summary
[edit]DescriptionVFPt fanselau coil.svg |
English: Magnetic field around a Fanselau coil[1] consisting of four round current loops symmetric around their common axis with identical current. This arrangement removes variations in the magnetic field, up to its 5th-order derivative with respect to the center. The inner loops have an axial position and radius . The outer loops have an axial position and radius . The current through all loops is . The central magnetic field is . |
