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...

A set of "Helmholtz" coils is a pair of identical coils, each having radius a, N turns, and current I. They are positioned a distance a apart with the axis of each coil on the x-axis. Each coil is parallel to the y-z plane, as shown. The origin is halfway between the coils. a) Determine the magnetic field magnitude and direction at any position x on the x-axis. b) Graph this magnetic field magnitude as a function of x, for...

Finding the charge to mass (e/m) ratio of the electron Often in physics, we look for ways to find fundamental physical constants. From the set-up demonstrated in class, we are able to find a monumental combination of two physical constants-the charge of an electron (e) and the mass of an electron (m). Since the charge of an electron (e) is well known through other experiments, we will use the ratio of charge to mass to find the mass of an...
