![]() ![]() Try setting the magnetic or the electric field to zero to see the effect of just one field on the particle. Since the particle is negatively charged, the electric field exerts an upward force ( F = q E see, for example, Illustration 23.4) and the magnetic field initially exerts a downward force ( F = q v x B). The particle initially enters a region with an electric field directed downward and a magnetic field directed into the screen. You can enter values for the initial conditions and then press the "register values and play" button to see a single particle pass through the mass spectrometer. Notice how the particles are separated based on their mass. The particles have different masses but are otherwise identical. This shows five particles passing through a model of a mass spectrometer. ![]() Please wait for the animation to completely load.īegin this animation by selecting the Multiple Masses Demonstration.
