Motors, Generators, and Source Ledgers

Magnetic Source Ledgers Close the Chain

The final lesson keeps magnetic sources visible instead of hiding an audit. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

Each magnetic claim keeps its own checked source

The force source is 24 newtons, the flux change is 12 webers, and the induced voltage is 4 volts.

The final source ledgers stay readable

Transformer power is 12 watts, and generator energy is 60 joules. The lesson shows sources instead of an opaque audit.
