Electricity & Magnetism: Introduction

or

Curriculum Module

Created with R2024a. Compatible with R2024a and later releases.

Information

This curriculum module contains interactive MATLAB® live scripts 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

These live scripts can be used as demonstrations in lectures, class activities, or interactive assignments outside class. This module covers electric fields and charge, magnetic fields and current, and the governing physical equations of electricity and magnetism. It also includes examples of applications like DC motors, capacitors, and magnetic braking.

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.

Solutions are available upon instructor request. Contact the MathWorks teaching resources team 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
