We practiced more on our two right hand rules, one to tell us how magnetic fields wrap around electric currents and one to tell us the direction of the force exerted on moving charged particles and currents. We also saw the fundamental relationship that we exploit in mass spectrometers, tools used to identify unknown substances. In which direction does the magnetic field point in this mass spectrometer in order to cause the positively charged particles to curve to the left as shown. Note that the particles start their journey from the right side of this mass spectrometer. [Answer: Vertically downward]
