ONE BIG IDEA
Electric current means moving charge. Machines transform energy; they don’t make energy from nothing.

What the model calculates
How to read the picture
Yellow dots show conventional current direction in wires, not individual electrons moving at their real speed. Electrons in metal move the opposite way. Field lines are a drawing of a field, not physical strings. Coils, charges and solar layers are enlarged for learning.
These are safe virtual experiments. If you build a real circuit, use a supervised low-voltage kit. Never connect a homemade experiment to a wall socket.
