Helmholtz coils are frequently used in experiments because they create a uniform magnetic field about their axial direction.Ma Helmholtz coils are frequently used in experiments because they create a uniform magnetic field about their axial direction. For example, they are traditionally used in the experiment for the measurement of the charge to mass ratio of the electron. Helmholtz coils are two coils separated by a distance equal to their radius and also carry equal currents in the same direction, as shown in the figure on the right. Suppose the radius of the coils is 12.00 cm, each coil carries a current of 11.00 A and have 360.0 turns. The coils are in the yz plane where one coils center is at x 0 the other coils center is at x R. Using the Biot-Savart law, what is the expression for the resultant magnetic field, Bx, along the line x joining their centers Express the magnetic field in terms of the radius of the coils R, the number of turns N, the current I, x, and the permeability of free space, Ho (Scroll down for more questions.)
