you need to build a fast homopolar motor 1) cylindrical neodymium magnet (more powerful is better) 2) 1.2 V rechargeable battery (delivers more energy per unit of time than the 1.5V battery) 3) washer used as a guide 4) copper wire suitably shaped 钕高速单极电机
I think that its functioning is possible for a small imperfection in the coil of copper. If the coil is perfectly symmetrical, the motor stops. The irregularity is “jumping” the coil at its sites of rotation, creating a discontinuous feed. 令人难以置信的钕磁铁电机
