Consider a charged particle moving through a region in which the electric field is perpendicular to the magnetic field, with both fields perpendicular to the initial velocity of the particle (see figure below). Such a device is called a velocity selector because for one particular value of the particle speed select the particle will travel straight through the device without being deflected, whereas particles with speeds that are either less than or greater than Vselect will be deflected. Consider a case with E = 505 V/m and B = 0.11 T.
