Taiwan geomagnetic field measurement project

Highlights International Connections
Event Date | 2022/07/01 - 2023/06/30 Address |

It is expected to promote the use of mobile phones in all parts of Taiwan to engage in geomagnetic measurement and research on geomagnetic changes. In order to obtain geomagnetic data from various places, a Taiwan geomagnetic census and time-varying changes are made in combination with the location of schools at all levels, especially elementary schools with high popularity. And through this activity, let students understand magnetism and care about geomagnetic changes.

The Taiwan Geomagnetic Measurement Project primarily aims to collaboratively involve elementary, junior high, and senior high school teachers and students across Taiwan. Over a year-long period, participants systematically measure changes in Taiwan's geomagnetic field to create a comprehensive geomagnetic map of the region. All data collected will be made available to the public at no charge. In tandem, we are collaborating with partners located at the antipodal point to Taiwan - Buenos Aires, Argentina - to compare and analyze measurement data, offering educators and students insights into whether geomagnetic fields exhibit geometric symmetry.

Measurement methods involve utilizing the Phyphox APP, harnessing the magnetometers in smartphones for data collection. Participating schools from all over Taiwan conduct measurements every 15 days, documenting the direction and intensity of the geomagnetic field, accompanied by photographs taken during the process. Findings are subsequently uploaded to a designated Google Forms. This initiative spans from July 2022 to July 2023, concluding with an aggregation and analysis of the geomagnetic changes observed throughout the year. Results will be compiled, visualized, and shared via bilingual videos on platforms such as YouTube and Facebook. Furthermore, raw data will be perpetually available on the official website for public access.

Throughout the project, 34 schools participated in its entirety (1 university, 26 high schools, 6 junior high schools, and 1 elementary school), with 151 educators and students (1 university, 263 high school students, 11 junior high students, and 1 elementary student) completing all measurements. Additionally, the initiative reached an estimated 276 individuals. A total of 2,109 valid data entries were collected, with an overall data count of 2,217. The covered regions encompass 6 cities and 12 counties, including the outlying islands of Kinmen and Penghu. To bolster outreach and education, various resources were generated: 5 teaching documents, 6 instructional videos, and 98 event videos, amassing 6,573 views as of July 30, 2023. Additionally, 4 educational tools were crafted, further underscoring the project's significant educational implications.
