You have often seen in the shops in the shops small pendulums in the form of a wide variety of figures. The principle of their work is based on the work of the simplest electric motor operating under the action of Ampere forces.
In our video, we suggest you familiarize yourself with how you can create such an electric motor in home conditions and make a small pendulum for your desktop.
To create a small electric motor we need:
- two large paper clips;
- battery;
- adhesive tape;
- wire;
- knife;
- chewing gum or plasticine;
- a magnet.
We take large clips, 2 pieces and bend the outer tip in a circle, creating to some extent a small loop. Next, we take the battery and the side that is the plus, we attach it to the clip so that the battery’s tip is in the opposite part of the clip from the loop we made. We fix the structure with a thin piece of adhesive tape.
We attach the second clip in exactly the same way to the second, minus side of the battery, securing it with tape too.
We wind the wire on a finger in the form of a spiral so that the turns lie as close as possible to each other, about 10-15 turns. With the ends of the wire we fix the made turns.
The remaining ends of the wire after fixing should be directed in exactly opposite directions. align them with a knife.
We install our battery in a horizontal position in this way. To keep the paper clips pointing up. We attach it to a flat surface with a piece of chewing gum or plasticine.
We put a small piece of magnet on the battery.
In the loops that we made, bending with clips, we insert the tips of the aligned wire. We center a little and remove our hands. When an electric current passes through a circuit formed by a paper clip and a twisted wire, the wire located in a magnetic field begins to rotate rapidly under the action of the Ampere force according to the Burawchik rule.
