This activity uses electromagnetic induction to measure pendulum vibrations in real time, allowing students to analyze the data and define thresholds to differentiate normal environmental vibrations from earthquake-like movements.If the defined threshold is exceeded, a buzzer alert is triggered, enabling students to investigate how earthquake detection and early warning systems work.

Learn how a moving magnet creates electricity by inducing current in a coil.

Observe how amplitude and period change over time (e.g., damped oscillation) through data analysis.

By converting the abstract principle of electromagnetic induction into visible real-time data graphs, students can strengthen their data literacy skills through hands-on experience with sensor data.
