The Earth’s Magnetic Field: Experiments with helmholtz coils, compass and smartphones (iStage 2)


The Earth’s magnetic field is responsible for the presence of the auroras in the polar regions and the beneficial deflection of the solar winds. It is the Earth’s safeguard against cosmic radiation and charged particles. In the teaching unit ‘The Earth’s Magnetic Field’ students learn how to measure the earth’s magnetic field. They test different methods, and, amongst others, also use special apps on their smartphones.

For this teaching unit the students should be at an age between 12 and 19 years, for certain knowledge in physics, mathematics, geography and ICT is presumed.

The project is taken from the brochure ‘iStage 2: Smartphones in Science Teaching’ from the topic ‘hands’. The complete brochure can be ordered free of charge (Mail at or downloaded. It was developed by 20 teachers from 14 countries around Europe. The project was proudly supported by SAP.
