Teen innovators build a low-cost magnetometer for national science finals

Two students from Braunschweig have earned a place in the national finals of Jugend forscht with their innovative physics project. Oleksandra Kompanets and Dominik Kultys, both from Hoffmann-von-Fallersleben School, developed a low-cost magnetometer that measures Earth’s magnetic field with remarkable precision. Their work has already won top prizes at regional and state levels.

The project, named 3G-Magnetix, uses disposable materials to create an affordable yet highly accurate device. It can detect magnetic fluctuations down to 1 nanotesla, making it capable of tracking magnetic storms. The duo’s achievement has drawn attention for its practicality and scientific rigour.

As part of their research, Kompanets and Kultys were invited to visit the Quantum Frontiers Cluster of Excellence. There, they toured advanced laboratories and conducted experiments to refine their work. Their success has since inspired younger students interested in science. Kompanets, originally from Ukraine, nurtured her passion for physics through a specialised school and a local physics club. Kultys, meanwhile, brings years of experience to the team—he has participated in *Jugend forscht* for six years and completed ten projects. Together, they secured first place in both regional and state competitions, along with several special awards. The pair will now compete in the physics category at the national finals, held in Herzogenaurach from May 28 to 31. Their project stands out for its blend of accessibility and high-level technical skill.

The students’ magnetometer demonstrates how simple materials can achieve advanced scientific results. Their success at regional and state levels has set high expectations for the national competition. The finals will determine whether 3G-Magnetix earns further recognition on Germany’s biggest stage for young researchers.
