About Charges and Fields
Arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. Plot equipotential lines and discover their relationship to the electric field. Create models of dipoles, capacitors, and more!
How to play Charges and Fields
Everything is hands-on: drag, click and experiment — the simulation reacts instantly. Arrange positive and negative charges in space and view the resulting electric field and electrostatic potential.
Questions & answers
- What is Charges and Fields?
- Charges and Fields is a free interactive simulation from PhET Interactive Simulations (University of Colorado Boulder) that you can play right in your browser on crumble.lol — no downloads and no sign-up. Arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. Plot equipotential lines and discover their relationship to the electric field.
- What can kids learn from Charges and Fields?
- It helps kids explore: determine the variables that affect the strength and direction of the electric field for a static arrangement of charges. investigate the variables that affect the strength of the electrostatic potential (voltage). explain equipotential lines and compare them to the electric field lines. for an arrangement of static charges, predict the electric field lines. verify the prediction using vector addition.
- What age is Charges and Fields good for?
- It is designed for middle school (roughly ages 10–14) up to university, and curious kids outside that range can absolutely enjoy poking around it too.
- Is Charges and Fields free to play?
- Yes — Charges and Fields is completely free on crumble.lol and runs fully in your browser on computers and tablets.
