DIY Simple Motor
Wrap the enameled copper wire around a circle with a diameter of 3cm and set aside the shaft on both sides.
Use sandpaper to polish away the enamel on the rotating shafts at both ends of the coil. If the enamel is not polished the coil will be in poor electrical conductivity which will cause it to fail to turn after being energized.
Then after fixing the battery box with 2 AA batteries, putting the magnets at the base and installing the coil on the L-shaped hole frames, the coil should start turning.
For the construction (assembly) and operation of the Simple Motor : a small screwdriver and 2x AA batteries are required and not included.
