Figure (a) shows a length of wire carrying a current i and bent into a circular coil of one turn. In Figure (b) the same length of wire has been bent to give a coil of 6 turns, each of 1/6 the original radius. (a) If Ba and Bb are the magnitudes of the magnetic fields at the centers of the two coils, what is the ratioBb/Ba? (b) What is the ratio

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 coils can be ignored a) Find the magnetic field B on the axis of symmetry (the r-axis) of the Helmholtz...

Helmholtz coils are two circular coils with radius R, each wound with N turns of wire carrying a current I, circulating in the same direction in both coils. The coils are placed distance R apart. The Helmholtz coil produce a very uniform magnetic field in the region between them. Obtain an expression for the magnitude of the magnetic field at point P, which is midway between the coils.
