To become familiar with the order of magnitude of magnetic effects, consider the situation in a television cathode ray tube (not a flat-panel tv). in order to bend the electron trajectory so that the electron hits the top of the screen rather than going straight through to the center of the screen, you need a radius of curvature in the magnetic field of about r = 19 cm (see figure below). if the electrons are accelerated through a 15,051 v potential difference, they have a speed of 0.712 ? 108 m/s. to become familiar with the order of magnitude ofcalculate the magnitude of the magnetic field required to make the electrons hit the top of the t
