Students use a simple set up consisting of a coil of wire and a magnet to visualize induced EMF. First, students move a coil of wire near a magnet and observe the voltage that results. They then experiment with moving the wire, magnet, and a second, current carrying coil. Students connect the coil to a circuit and the current from the induced EMF charges a conductor.

In this service-learning engineering project, students follow the steps of the engineering design process to design an assistive eating device for a client. More specifically, they design a prototype device to help a young girl who has a medical condition that restricts the motion of her joints. Her wish is to eat her favorite food, pizza, without getting her nose wet. Students learn about arthrogryposis and how it affects the human body as they act as engineers to find a solution to this open-ended design challenge and build a working prototype. This project works even better if you arrange for a client in your own community.

In this fun, engaging activity, students are introduced to a unique type of fluid—ferrofluids—whose shape can be influenced by magnetic fields! Students act as materials engineers and create their own ferrofluids. They are challenged to make magnetic ink out of ferrofluids and test their creations to see if they work. Concurrently, they learn more about magnetism, surfactants and nanotechnology. As they observe fluid properties as a standalone-fluid and under an imposed magnetic field, they come to understand the components of ferrofluids and their functionality.

Students are introduced to a unique fluid—ferrofluids—the shape of which can be influenced by magnetic fields. This activity supplements traditional magnetism activities and offers comparisons between large-scale materials and nanomaterials.Students are introduced to the concepts of magnetism, surfactants and nanotechnology by relating movie magic to practical science. Students observe ferrofluid properties as a stand-alone fluid and under an imposed magnetic field. They learn about the components of ferrofluids and their functionality as they create shapes using magnetically controlled ferrofluids and create their masterpieces.
