"WebIf you use 8 or fewer layers, the Shupe sensitivity will be worse than that of an SMF coil. Of course, to prevent such deterioration completely, the number of layers should not be changed (m = M). If the coil diameter is not changed, the number of turns in each layer can be reduced to 1/N c. In this case, the Shupe sensitivity is improved to 1/N c. " - Shupe effect
