if the accelerating voltage remains constant but the current through the Helmholtz coils is increased, what would be the effect on the radius of the circular motion of the electrons?
we know, B = mue*n*I
and r = m*v/B*q (radius of path of electron)
if cuurent increases to 2 times, Be increases to 2 times
so, r' = r/2
if the accelerating voltage remains constant but the current through the Helmholtz coils is increased, what...
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.
Describe what happens to the electron beam path when the current through the Helmholtz coils increases or decreases. Write only 2 or 3 sentences.
A Helmholtz Coil with R = 5cm is a pair of coils with the same
co-axial separation as radius. What is the magnitude of the
magnetic field at the center of the Helmholtz Coil with a pair of
500 turn coils with a 15 A of current?
A set of Helmholtz coils has a coil diameter of D = 0.062 m , with N = 18 turns in each coil, and the current flowing through the coils is I = 1.6 A. What will the magnitude of the magnetic field at the centre of the Helmholtz coils be? Express answer to two significant figures.
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,...

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...
Why would the slope of the graph of Fz vs dBz/dz for helmholtz coils increase as I increases instead of remain constant? Fz=magnetic force, dBz/dz=field gradient, I=current
