Since your team was so successful at creating the magnetic field detector, the Lakeviewians have now hired you to analyze other characteristics of the mystery particles. The particles appear to have a variety of masses, so you start by trying to sort the particles by mass for further analysis (using a mass spectrometer). Before building the spectrometer, your team is asked to develop a model of the spectrometer. The higher ups have specified that they would like to use a constant magnetic field of 2 T and to isolate the effects of the B-field within the magnetic housing box, but they are unsure what direction the magnetic field should be relative to the catching plate. Below is the beginning of a model that was developed by another team that mysteriously disappeared.
GlowScript 3.0 VPython ## Model parameters B = vec(0,0,0) ## Objects mag_housing = box(pos=vec(1,0,0), length=2, height=2, width=2, opacity=0.2) catchingplate = box(pos=vec(4,0,0), length=0.1, height=10, width=10, opacity=1) xaxis = cylinder(pos=vector(-3,0,0), axis=vector(6,0,0), radius = 0.05, color=color.white) yaxis = cylinder(pos=vector(0,-3,0), axis=vector(0,6,0), radius = 0.05, color=color.white) zaxis = cylinder(pos=vector(0,0,-3), axis=vector(0,0,6), radius = 0.05, color=color.white) ## Set up particles (DO NOT EDIT LIST) i = 0 N = 20 particleList = [] while i < N: particleList.append(sphere(pos=vec(-2-4*random(),0,0), radius = 0.1, m = 20*(random()+1), v = vec(2,0,0), q = 10, color=color.red)) i = i + 1 ## Calculation Loop t = 0 dt = 0.01 while t < 30: rate(300) for thisParticle in particleList: thisParticle.pos = thisParticle.pos + thisParticle.v*dt if thisParticle.pos.x > catchingplate.pos.x: thisParticle.v = vector(0,0,0) t = t + dt
