Warning: Disconnect the electric motor when not using, or after a few minutes of use because the circuit will get hot.
Building an electric motor requires patience and tinkering. If your motor doesn’t work, check this:
Building an electric motor requires patience and tinkering. If your motor doesn’t work, check this:
- Is it on a level surface?
- Is the coil well balanced? It should spin without wobbling.
- Try spinning the coil in both directions. It may work in one direction but not the other.
- Make sure the wires are making good electrical contact with the battery terminals and the paper clips.
- Flip the magnets over so that the opposite pole is facing the coil.
- Make sure the insulation is completely scraped off the arms of the coil.
- Check the clearance between the bottom of the coil and the magnets. It should be about 1 centimeter.
- Make sure the loops in the paper-clip holders are about the same height.
