Fields

Visualize the electric field resulting from systems of charged particles

Fields is an easy-to-use, free sandbox app that helps you visualize the electric field resulting from systems of charged particles that you design and manipulate.

This app is perfect for those wishing to gain better intuition about electric fields or those who just want to be mesmerized by the beautiful electric field patterns that charged particles can produce.

Add positive and negative charges to the screen. Drag charges around the screen and watch the electric field lines update in real time. Visualize the field of an electric dipole or quadrupole. Create complex and interesting charge configurations. Save your charge distribution for later.
