**Curriculum Module**



_Created with R2024b. Compatible with R2024b and later releases._



# Information



This curriculum module contains interactive [MATLAB® live scripts](https://www.mathworks.com/products/matlab/live-editor.html) that provides supplementary examples and visualizations to enhance understanding of electricity and magnetism principles, specifically focusing on common application like capacitors and DC motors.






## Background



This initial release of the Electricity & Magnetism courseware features two interactive scripts that explore the principles of how capacitors function, based on the laws of electrostatics.



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 image_0.png Stop button in the **RUN** section of the **Live Editor** tab in the MATLAB Toolstrip.



## Contact Us



Solutions are available upon instructor request. Contact the [MathWorks Educator Content Development Team](mailto:onlineteaching@mathworks.com) if you would like to provide feedback, or if you have a question.






## Prerequisites



This module assumes knowledge of basic calculus and introductory physics, including mechanics and fundamental concepts of electricity and magnetism.






## Getting Started

### Accessing the Module

### **On MATLAB Online:**



Use the [image_1.png](https://matlab.mathworks.com/open/github/v1?repo=MathWorks-Teaching-Resources/emag&project=emag.prj) 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.



### **On Desktop:**



Download or clone this repository. Open MATLAB, navigate to the folder containing these scripts and double\-click on [emag.prj](). It will add the appropriate files to your MATLAB path and open an app that asks you where you would like to start. 



Ensure you have all the required products ([listed below](#H_E850B4FF)) installed. If you need to include a product, add it using the Add\-On Explorer. To install an add\-on, go to the **Home** tab and select  image_2.png **Add-Ons** > **Get Add-Ons**.
