The principles of electromagnetism are often taught in a very abstract way, and students can struggle to link the concepts with real life.

Overview

In this activity, students are tasked with winding their own electromagnets and building a working brushless DC motor. Before connecting their motor to a provided test bench, the students must first determine the activation sequence for the electromagnetic coils, and test this sequence using switches to activate each coil at the right moment. This way, students are given the opportunity to plan and predict, then evaluate their actions based off of these predictions.

A brushed version of this motor is currently under active development.
