Why it works
The first 0:28 ties the hidden mechanism to household devices and asks a clear how-question before teaching parts. Across the measured six minutes, 68 internal picture changes keep one 3D workspace active while the explanation builds from circuit to magnet to motor. The 5:03–5:08 replay peak falls as the brushes meet the split commutator, the key step that automates the earlier manual reversal.
