Electric Field near Conductors
Electric Field near Conductors
Understanding how conductors interact with electric fields is critical, yet visualizing them in 3D can be a challenge — until now!
I am excited to share an interactive 3D electric field visualizer near a conductor that allows you to:
- Choose between two conductor configurations:
- A grounded conducting plane.
- A grounded conducting sphere.
- Watch how the electric field lines automatically update in real-time based on the charge’s position.
- Toggle between configurations and streamline visibility using the simple UI overlay.
💡 What’s Happening Behind the Scenes?
The method of images to simulate how conductors alter the field pattern:
- For the plane, a mirror image charge is created.
- For the sphere, an image charge is calculated using the classic result from electrostatics.
The electric field is computed numerically and visualized using streamlines. Their color changes with field strength, giving you both direction and intensity information.
🛠 Built With
- Three.js for 3D rendering
- JavaScript modules for real-time field calculations
- Custom streamline tracing logic using Catmull-Rom curves
📬 Let me know what features you’d like to see next — multiple charges? Capacitor plates?
