Developed by Emily Waite and Prof. Daniel Shoemaker

While there are websites that describe how to build speakers from common items, the implementation can require precision that can be frustrating for younger students, not to mention time consuming. We developed a kit that is based on simple 3D printed parts, which can be easily printed, and detailed instructions to ensure success for students, while still leaving opportunities for tinkering and open-ended discovery.

We have created a folder of resources that are FREE to use, including:

·       Files for 3D printing the base and coil

·       List of materials to purchase, including a shopping list

·       Instructions on putting together the kits

·       Student instruction handout

If you use the kit materials, we would love to hear about your experiences. Please e-mail Pam Pena Martin ([email protected]).

If you are in the Champaign-Urbana area, we may be able to lend you kit materials! Reach out to inquire.

We gratefully acknowledge the support of the American Physical Society (APS) Topical Group on Magnetism and its Applications (GMAG) for funding to create these kits, and additional support by the Illinois Materials Research Science and Engineering Center under grants DMR-1720633 and DMR-2309037.
