Do you want to make a motor to impress your friends, set something in motion or just like that? It's amazingly simple.

Steps

1. 1 Take a size AA battery and wrap the wire tightly around it at least 20 times, about 5 cm from the ends of the wire. The tighter the winding, the better.
2. 2 Tie the ends of the wire around the resulting ring with simple knots to secure the coil. Position the knots so that the line connecting them goes through the center of the coil.
3. 3 Strip the insulation off half of the wire from both ends protruding from the coil. If there is no insulation on the wire, you can leave it as it is.
4. 4 In order to make two loops on which the coil will hold and connect it to the battery, you will need two pieces of stripped wire.
5. 5 Place a magnet under the coil, fasten the holders, shake the coil and it should start spinning.

Tips

• To make a simple switch, tuck a piece of paper between the positive (+) end of the battery and the holder. By pulling out the piece of paper, you will close the circuit and the motor will start to rotate.
• Paper clips are great for use as holders.
• The best for the coil is a wire with a diameter of 0.644 mm in enamel insulation.

Warnings

• Always be careful with electricity. But, in general, an AA size battery is safe enough.
