I know that cathode rays follow a helical pattern if they enter a uniform magnetic field at an angle less than 90 degrees. This leaves me with two questions.
1. If the cathode ray described above, hit a phosphor coated screen, would it show only 1 spot or a circle?
2. If the magnetic field was constantly changing in strength, would the spot trace a path of spiral, concentric circles or some other shape?
