This experiment investigates how the magnetic force between two permanent magnets changes as the distance between them increases. By measuring force at different separations and analyzing the data graphically, the experiment reveals how magnetic interactions weaken with distance and demonstrates quantitative experimental analysis in physics.

Batteries power everything from flashlights to smartphones, but few people think about what happens inside them when current flows. In this experiment, we explore how the internal resistance of a common AA battery affects its terminal voltage as current increases.

This experiment demonstrates how biodegradable materials and conductive inks can be used to build electronic circuits that function normally yet decompose naturally over time, showcasing a sustainable approach to reducing e-waste.
