TX-11 - Electric STEM Kit - Electromagnetic Swing

Electromagnetic Swing ⭐⭐⭐ · ~30 min

ENGLISH

⚡ Principle This kit uses the principle of magnetic repulsion. When the battery is connected, the copper coil becomes an electromagnet. Since its magnetic pole is the same as the magnet below, they repel each other, pushing the swing into motion.

🔩 Parts

Wooden boards (frame and base)

Copper wire ×1

Sheep eye nails (hanging hooks) ×2

Magnets ×2

Battery holder ×1

Foam adhesive ×1

📋 Steps

1. Scrape off the insulation (the clear coating) from both ends of the copper wire. Wrap the wire around wooden boards 6 and 7 to form a coil, then bend the ends into small hooks.

2. Assemble the swing frame using boards 1, 2, 4, and 5. Use foam adhesive to stick the battery holder onto board 2.

3. Screw the two sheep eye nails into board 3.

4. Install the bracket into board 3, then hang your copper coil. Place the two magnets on the base directly under the swing. Install the battery, give it a tiny push, and watch the magnetic magic!

⚡ Fun Fact! Maglev trains in Japan and China use this same principle of magnetic repulsion to "float" above the tracks, allowing them to travel at speeds over 600 km/h!

💚 Tip The most important part is scraping the ends of the copper wire until you see the shiny metal. If the insulation isn't removed, the electricity won't flow and the swing won't move!
