Draw a picture of the crt with an undeflected electron beam. since you will not be using electric fields, you do not need to include the deflection plates. draw a coordinate axis on this sketch and show a region occupied by a uniform magnetic field for part of the electron’s trajectory. determine the direction of this magnetic field to give maximum deflection. draw the electron’s path entering, through, and leaving this region of uniform magnetic field to show the beam deflection at the screen. also show vectors representing the electron’s velocity and acceleration in each part of the path.
