In a crt, a B field alters the paths of electrons which strike a phospour coating on the front of the tube causing them to glow. So, you move the electrons around which cause different parts of the CRT to glow. Basically you have a decent sized particle accelerator pointed at your face for 8-20 hours a day every day.
