Advanced Magnetic Coil System For Uniform Magnetic Field Intensity And High Accuracy

Abstract: The invention relates to an advanced magnetic coil system for producing uniform magnetic field intensity with high accuracy, comprising at least four metal formers releasably joined to each other, and each having at least one groove; at least four coils connected to each other by eight studs, the coils being disposed on the formers; the inner coils of said at least two coils carry at least seventy five percent of at least two outer coils current the two inner second and third coils are connected in series and excited with a current source, the two outer first and fourth coils are connected in series and excited with another current source, wherein the four coils has equal diameter and equal number of turns, wherein the distance between the first coil and the second coil or the third coil and the fourth coil is 48% of the coil diameter, wherein the distance between the second and the third coil is 42% of the coil diameter, and wherein the magnetic field distribution uniformity tolerance is achieved about 2%.
