Electrons is a charged particle simulator for iPad. It allows you to create dozens of positively or negatively charged particles, either freely roaming in space, or contained within conducting bodies. You can observe complex particle interactions and resulting electric forces, create capacitors, simulate a lightning rod, a cathode ray tube (CRT) and much, much more. Through play, you can effortlessly gain deeper understanding of many natural phenomena. Following the included guided tour of 10 experiments will give you further insights into the world of electricity.
A perfect companion for students and teachers of physics and electrical engineering, or anyone interested in understanding one of the four fundamental forces — the one without which there would be no lightbulbs or elevators, no radio and television, no computers, no Internet, and for that matter—no life.
Electrons app includes an 11-page guide, explaining the basics of electric forces and Coulomb's law, and provides 10 guided experiments, which you can try on your own. By following them, you will systematically unravel many of the seemingly puzzling mysteries of nature.
By following the guide, you can:
⊕ Get acquainted with the basics of attractive and repulsive forces.
⊕ Learn why electric field inside conductors equals zero.
⊕ Learn why electric field is stronger in corners and pointy edges.
⊕ Simulate an electrostatic shock (redistribution of charge).
⊕ Create a capacitor and observe its homogenous electric field.
⊕ Learn how to create a do-it-yourself electric field probe.
⊕ Learn how to neutralize electric field.
⊕ Demonstrate how a cathode ray tube deflects particles.
⊕ Simulate a lightning rod and observe how it "attracts" lightning.
How to use:
⊕ create charged particles by tapping or drawing a vector of initial velocity using your finger
⊕ draw conducting bodies by dragging your finger
⊕ move and delete conducting bodies
⊕ use two fingers to pan
⊕ toggle force display, grid display, change speed of simulation or force vector zoom
⊕ reset entire scene by pressing a button

Fun with magnetism
Doesn't show any curved fields but shows straight vectors. Fun to play with and teach kids about magnetism. It would be nice to draw custom shapes or at least rotate rectangles at an angle. It would be fine to have the option to show some of the mathematics behind is for educational purposes. Company produces some good apps, worth the price paid. Thanks.
Try this out it's fun! If you're into personal growth (science not so much) think about the negatives & positives as representing thoughts. Think of the bodies (circles & squares) as representing people. Very trippy when you discover the interactions!
Could use one simple fix
The ability to rotate the screen view! For educators using a tv display, it's a big let down. This is a simple fix, can you please make it happen?
With Family Sharing set up, up to six family members can use this app.
