Unipolar motor
- Transfer
To create the simplest unipolar engine, we need:
- AA battery
- Flat round neodymium magnet (for example, you can pull it out of the headphones)
- Copper wire
Under the cutscene, an instruction and video demonstrating the assembly process and the result.
- Place the magnet on the negative side of the battery. The magnet used in the example is 1.25 cm in diameter and 0.65 cm thick. Any magnet of a similar size will do, but ordinary ceramic magnets are too weak, so it’s better to use neodymium.
- If the wire has insulation, then it must be removed. Bend the wire to any shape you like, making sure that the resulting circuit has good contact with the positive terminal of the battery and around the circumference of the magnet. Giving the wire a beautiful and functional form requires some patience. As a basis, you can take the forms shown in the photographs.
- Balance the circuit on the battery and, making changes to it, make it rotate easily and quickly. The battery will last for several minutes.
