A bipolar neodymium ball magnet swings along an arc-shaped plastic track, delivering timed impulses to a Lego escapement wheel. As it rolls through an air-core coil, its polarity aligns with a bistable magnetic field controlled by a hidden multivibrator circuit. Each pass induces a counter-electromotive force (CEMF), reversing the field direction via Lenz’s law and sustaining the oscillation.
