Activity

Teach Engineering: Magnetic Fluids

Curated by ACT

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.
