Curriculum Module
Created with R2021a. Compatible with R2024a and later releases.
This curriculum module contains interactive MATLAB® live scripts and MATLAB® app that follow J.J. Thomson’s landmark experiment to measure the charge to mass ratio of the electron, e/m.
The app is a virtual replacement for the experimental apparatus commonly used in physics laboratories. The live script contains a manual for conducting the experiment. This lab includes background, pre-lab, virtual experiment, and data analysis sections and concludes with an application of the theory to mass spectrometry.
The instructions inside the live scripts will guide you through the exercises and activities. Get started with each live script by running it one section at a time. To stop running the script or a section midway (for example, when an animation is in progress), use the 
Stop button in the RUN section of the Live Editor tab in the MATLAB Toolstrip.
Contact the MathWorks teaching resources team if you would like to provide feedback, or if you have a question.
Use the 
link to download the module. You will be prompted to log in or create a MathWorks account. The project will be loaded, and you will see an app with several navigation options to get you started.
Download or clone this repository. Open MATLAB, navigate to the folder containing these scripts and double-click on virtual-measurement-of-the-electron-charge-to-m.prj. It will add the appropriate files to your MATLAB path and open an app that asks you where you would like to start.
