Static and Flowing Electricity

⚡ Hair sticking to a comb isn't creating new electricity! Electrons just moved from one side to the other, so the total charge is always 0. 🧪 Glass is fascinating: rub it with silk and it becomes positive, but rub it with fur and it becomes negative. The charge sign depends on the pair, not just the object! 🎈 Play with two balloons by changing their charges and distance to see how charge is proportional while distance works by inverse-square. 🔄 Finally, move a magnet in and out of a coil to generate current. Hold it still inside? Current drops to 0 — change creates current, not presence! Built with code · Remix it to add your own generator!

About this app
Still Electricity, Flowing Electricity is an interactive middle school science app covering static electricity, electric force, and electromagnetic induction. Explore how rubbing transfers electrons without creating charge, how charge signs and distance affect the force between balloons, and how a moving magnet produces current in a coil. Guided challenges, visual diagrams, selectable variables, and feedback make each concept easy to test.
Use cases
- Middle school students learning basic electricity and magnetism
- Teachers demonstrating static charge and electron transfer
- Learners exploring attraction and repulsion between charged objects
- Students investigating how distance and charge affect electric force
- Beginners studying electromagnetic induction through a coil and magnet
Features
- Interactive rubbing experiments with fur, glass, silk, and plastic pairs
- Electron-transfer controls showing opposite charges that sum to zero
- Balloon electric-force simulation with selectable signs, charge, and distance
- Visual comparison of attraction, repulsion, charge scaling, and inverse-square distance effects
- Coil-and-magnet induction simulation with pole, motion, speed, and turn controls
- Step-by-step challenges, reset and next controls, and explanatory feedback
