WebTo study the motion of electrons in a homogeneous magnetic field, you usually use a so-called filament beam tube, which you place inside a large pair of Helmholtz coils. Inside the cathode ray tube, an electron gun generates a fine electron beam with variable velocity. WebThe magnetic field B, like force fields g and E, fills three-dimensional space.

Helmholtz coil - Wikipedia

WebEquation (6) is the working equation for the apparatus used. The quantity within the first set of parentheses is constant for any given pair of Helmholtz coils. (For the Helmholtz coils with which we are working, the number of turns of wire N = 130 and the mean radius of the coils a is about 0.15 meters, but you Web18 mei 2024 · The field is only approximately homogeneous along a line extending from the centre of the coils. To find out how far the coils must be displaced, you need to set the condition that the curvature of the field at the centre be zero, $\frac{d^2B}{dx^2}=0$.To see why, we can expand the field about the centre point of the two coils, at this location the … mdu knife river spin off
