DIY Homopolar Motor; The Lorentz Force in Action

Today, we will be exploring the Lorentz Force and how you can use it to create your very own simple motor using electricity and magnetism! All you need to get started is 18 gauge copper wire, 1 AA battery, 1-2 disc magnets, wire cutters, and some pliers! Remember to ask an adult for help with cutting your wire!

An instructional graphic showing the materials needed to create a homopolar motor, including copper wire, a AA battery, disc magnets, wire cutters, and pliers, along with step-by-step directions for assembly.
