Using the principle of energized coils moving in a magnetic field, we designed a small technological production - a unipolar motor tram.
1. Material preparation: flat cardboard, aluminum foil, old clothes hangers, two round strong magnets (on men’s belt heads), pliers, files, glue, scissors, batteries, wires
2. First cut the aluminum foil paper into two long strips and stick them on the cardboard with glue (keep them parallel and leave a certain distance)
3. Connect the positive and negative poles of the power supply to one end of the glued aluminum foil paper
4. Use pliers to cut off a small section of the clothes hanger, and use a file to flatten both ends (into vertical sections)
5. Place two strong magnets on both ends of the polished iron bar, keeping the same poles facing each other (mutually repelling sides), and the car is ready

6. Try the effect. Place the car on the prepared track, turn on the power, and see if the car starts running!
