Very cool demo of mixed internal-combusion-engine and electro-magnetic motor

There is a small hesitation when you first plug it in, as I guess the AC to DC switching power supply needs a bit of time to power its output, but then the motor comes to live with high RPMs! The kids were fascinated by this. I explained the similarity (pistons pushing on a shared crankshaft/rod) and differences (driven by switching magnetic field instead of exploding gas/air mix) to an internal combustion engine.
