Problem 5 (25pts). A Helmholtz coil (see figure below) is a structure used for creating uniform magnetic fields at the centre. Consider two thin circular coaxial coils each of radius R, having N turns, carrying a current I in the same direction and separated by a distance d. The field due to the thin wire connecting the two...
