Induction Bench — Live Electromagnetic Field Lab
The Bugged Dev
@thebuggeddev · 14.7K followersA full electromagnetic induction lab that runs in the browser. A 3D magnet swings through a copper coil while glowing field lines, colored on a log scale from 1 mT to 1 T, curve around it. Beside the view sit a galvanometer, a live oscilloscope and a flux-linkage plot, all computed on the fly. You can swap magnet grades (N52, N42, SmCo, ferrite), coil wire (Cu, Ag, Al, NiCr), turn count, coil angle and core. Induced EMF, current and the force on the magnet update as you drag. Built with Claude Opus 5.5 by @thebuggeddev, who says seeing it visualized taught him more than any textbook.
- Real 3D field lines around a swinging magnet, with a log-scale color map of |B|
- Live galvanometer, oscilloscope and flux-linkage graph with EMF = -slope × speed
- Tweak magnet grade, wire material, turns, coil angle and core and watch the physics respond
“Maybe if physics had always been this easy to visualize and learn, we might have had more physicists than ever. AI is making learning so much easier to understand and actually fun. This is an electromagnetic field visualization built using Claude Opus 5.5. I do not think I have ever understood this subject better than I did by simply seeing it visualized like this 😅”
