Build circuits, trace magnetic fields, and see induction in action.
I = 0.000 A
Tip: Current I = V / R. Bulb brightness scales with current. Arrows show direction of conventional current.
N → S arrows
The bar magnet is modeled with two opposite “poles” at each end. Arrows indicate field direction; length hints magnitude.
Faraday’s Law: EMF ≈ - dΦ/dt. As the magnet moves through the coil, changing flux induces a voltage.
Watch the meter and coil color flip with EMF sign. Pause/resume with Space.
