Share a homemade mini maglev train tutorial. The maglev train uses the principle of magnets with same poles repelling and opposite poles attracting. This technology allows the train to travel suspended in the air and only generate friction with the air. It cannot reach speeds of hundreds of kilometers. question. A master teaches everyone how to make a simple mini maglev train using simple materials. Material preparation: two dry batteries, several strong magnetic magnets, and a bundle of thin copper wire.

Production steps: Wrap the copper wire around the battery tightly one by one. After winding, take off one coil. This is the "train track". The length is as long or short as you like; then put three magnets into a group. Two groups are needed to pull them together, one group is connected to the positive pole of the battery and the other is connected to the negative pole; finally, put the battery into the coil, and the battery with the magnet will pass across the inside of the copper coil. This is a simple version of the "maglev train" ".

If its not exciting enough, you can wind the coil longer and connect the two ends to form a closed loop. The battery can run continuously in the closed coil until the battery is exhausted.
