Electromagnetism 3D
Arrange magnets, wires, and solenoids and see the 3D field they create
Electromagnetism 3D is a free electromagnetic field simulator that runs in any browser and requires no installation. Build a scene from wires, solenoids, and permanent magnets, adjust their properties in an inspector, and watch the field update live in 2D or 3D. You can trace how charged particles move through the field, integrate Ampère's law along a path you draw, save and share scenes via URL, and embed simulations into class pages or LMS with a one-line iframe. It works on Chromebooks and is made for physics teachers and curious learners who want to see what electromagnetic fields actually look like, not just read equations about them.
