discount Autodesk Mudbox 2015 A magic eye is a simplistic triode tube that was used as a tuning indicator in radio receivers around the time of the World-War II. It has a bowl shaped anode coated with a phosphorescent material that produces a green glow when electrons strike on it. In this experiment, we measure the radius of curvature of the path of electrons in a magnetic field using a freeware, open-source image processor ImageJ, and calculate the charge-to-mass ratio of the electron.
