SimulationPower Strip Overload
In a 3D room on a winter morning, plug a hair dryer, heater and kettle into power strips and wall outlets yourself, and watch the currents of parallel appliances add up in one strip cord on current bars and a thermal camera. Measure voltages and currents of series and parallel connections with a multimeter on a lab bench, fix overloads and daisy chains, then choose safety rules with reasons.

SimulationSpeaker Workshop
Watch in slow motion how the force on a coil in a magnetic field moves the cone and the air inside a cutaway speaker, then design speakers from a paper cup, a plate or a foam board, measure their sound level and listen to them. Spin a motor that works the same way and sort materials by how a magnet attracts or repels them.

SimulationOhm's law bench
First predict what doubling the voltage does to the current. Then set the voltage and the nichrome wire's length and thickness, plot the readings on a voltage–current graph (voltage across, current up), work out the resistance as voltage ÷ current, and compare with the prediction.

SimulationUpdatedOct 31Running the Town's Power Grid
In a 3D town with nuclear, coal, hydro, solar and wind plants, set plant output and transmission voltage through one day to keep the lights on. Trace energy conversion and efficiency inside a coal plant, see I = P/V and the I²R loss on the line, and test turns ratios and why a transformer needs AC.

2:12VideoElectromagnetic Induction: Magnets, Coils and Generators
A 3D look at how a changing number of magnetic field lines through a coil drives an induced current, leading on to rotating-coil generators and energy conversion in power plants. No narration; explained through subtitles.

SimulationElectric Field Topography
Point charges raise a 3D landscape whose height and colour show the electric potential, with equipotentials and field lines drawn on it. Release test charges, measure with a probe to check E = kq/r² and superposition, then read ready-made maps to infer field direction, strength and charges hidden under clouds.

SimulationAurora Factory
Fire electrons, protons and neutrons into a coil-driven magnetic field to find when the Lorentz force appears and why charges circle and spiral, watch Earth's dipole field deflect the solar wind, and send particles along field lines to build the Van Allen belts and light auroras (green and red oxygen, violet nitrogen). Finish by running a wire swing, a circular accelerator and a tokamak.
