You won’t believe what can be made of ordinary copper magnet wire and batteries. By the way, not only copper wire can be used in the same way as a battery can be used not necessarily with a finger. In general, to make a simple primitive motor, you need any battery magnet and wire.
Those who do not like to read (like me for example) suggest immediately watching the video below.
By the way, it’s worth adding that the video shows 3 tricks with a magnet, so I recommend everyone to watch it. In this post I will briefly describe only a way to make a motor. And so for the implementation, you need to prepare a wire magnet (in my case neodymium) and a battery (not salt). We take the wire and form it from it as shown in the picture below. It is possible to completely clean from insulation or it is possible to clean only places as shown in the example picture.
Now we attach the magnet to the negative part of the battery and put it on some surface (in my case, on the table).
After that, we put our wire construction on top of the battery with a magnet and, if necessary, give the starting kick so that the motor spins.
That's all friends. Enjoy your viewing and have a nice day. Write your comments and suggestions in the comments.
