Principle: 
The closed coil rotates in the magnetic field, and the inductive current is generated by electromagnetic induction, so the principle of its generation is battery induction.

Methods of assembly: 
Step 1: stick four small squares to the four corners of the board with white glue.
Step 2: glue the frame with white glue. The glue is not dry at this time. so we need to take it lightly and put it lightly.
Step 3: connect the whole frame with glue. Wait for 15-20 minutes until glue to solidify.
Step 4: after glue solidification, assemble the drive shaft with yellow sleeve clamp, small white rotating axis toward the inside.
Step 5: install swing arm and drive wheel, and use yellow sleeve clamp. 
Step 6: tie the motor bracket under the skew beam with the strapping band, or put it flat on the board. Install the motor.
Step 7: install a belt, a short belt for the top wheel, a long belt to connect the motor wheel and the top;
Step 8: use double-sided adhesive to fix USB plate, red wire to positive pole, black wire to negative electrode, complete assembly. Because the circuit needs a steady current to start off, speed up a few laps (or pick up a belt bomb several times) until the lights turn on to slow down the speed.
