Turns Multiply Flux Linkage

A coil turn count multiplies the flux-change ledger. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

With 2 turns and flux change 6 webers per turn, linkage change is 12 webers.

\Delta\lambda=2\times6=12\ \mathrm{Wb}

Linkage change over time gives voltage

The linkage change 12 webers over 3 seconds gives 4 volts.

V=12/3=4\ \mathrm{V}
