7) Maximum V and minimum I produce largest value of radius r for electron beam path .
8) if radius of Helmholtz coil increases by a factor of 2 then, e/m factor also gets increased by a factor of 4 as e/m is directly proportional to square of radius of Helmholtz coil.

27B -- Experiment: Magnetic Force on a Moving Charge - qolme Objective: In this module you will observe the trajectory of an electron beam in a uniform magnetic field oriented in various ways to the electron velocity. You will then use your observation of the radius of the electron trajectory to measure the charge to mass ratio for an electron. Equipment: One elm apparatus (Lurge mounted glass bulb with Helmholtz coils); one Leybold or PASCO power supply for electron gun...

Finding the charge to mass (e/m) ratio of the electron Often in physics, we look for ways to find fundamental physical constants. From the set-up demonstrated in class, we are able to find a monumental combination of two physical constants-the charge of an electron (e) and the mass of an electron (m). Since the charge of an electron (e) is well known through other experiments, we will use the ratio of charge to mass to find the mass of an...

You are working with a team to design a better electron microscope. To precisely control the beam of electrons, your research team decides to try a magnetic field. For your study of electron control you decide to use a Cathode Ray Tube (CRT) with a magnetic field perpendicular to its axis. From your work with Helmholtz coils in the earlier problem, Measuring the Magnetic Field in Two Parallel Coils, you know that the magnetic field between these parallel coils is...
