Illustration of how to make scientific inventions of simple electric motor childrens toys

The method of making this electric motor toy is quite good Simple, first prepare an AA battery, a hard copper wire, and a permanent magnet. This is all the materials. After it is built, the copper ring will rotate at high speed, which is very interesting. Can be used to inspire the next generation of electronics enthusiasts.
All preparation materials:

The battery must be selected to be magnetized sucking

The magnet should be the same diameter as the battery and should be With conductive metal coating

Suck on the negative terminal of the battery and ensure there is no short circuit

Fold the copper wire as shown in the picture shape, and can also be folded into more interesting lines

It should be noted that the copper wire below The two sides cannot touch the magnet at the same time, and a gap must be left.

Adjust the upper and lower heights so that the current can pass through the copper wire on one side to create a loop at a certain time

Place the copper wire as shown below on battery

The small motor started to rotate. Friends who are interested can try it themselves.
