Statement 1:
When the magnet in the core device "pressure generator" cuts the magnetic induction line and the magnet is reset, it can also cut the magnetic induction line, thus generating alternating current. Then it is converted into direct current by the installed full-bridge rectifier stack, and then stored by the filter capacitor, which can be used for lighting and charging.
Statement 2:
1 is the change of magnetic flux.
2. The circuit is closed
When the conductor cuts the magnetic induction line in the magnetic field, the induced electromotive force is generated, and when the loop is closed, the current is generated.
Composition: Generator usually consists of stator, rotor, end cover and bearing.
Stator is composed of stator core, winding, frame and other structural components for fixing these components.
The rotor consists of rotor core (or magnetic pole, yoke) winding, retaining ring, center ring, slip ring, fan and rotating shaft.
The stator and rotor of the generator are connected and assembled through the bearing and the end cover, so that the rotor rotates in the stator and cuts the magnetic field lines to generate an induced potential, which is led out through the terminal and connected to the loop to generate current.

Appendix 4: Summary of Related Issues (Known)
Question: What is the power generation rate of the self-made generator?
Answer: The efficiency of self-made small permanent magnet DC generator can reach 80-95%, but the output voltage of permanent magnet generator is not very stable. In order to obtain stable voltage, it is necessary to make excitation generators, such as ordinary silicon rectifier generators for vehicles, but the efficiency will be slightly lower, generally 75-90%.

Question: Minimum revolution requirements for self-made small generators.
Answer: The electric power of 1-3W can be obtained by modifying the DC motor. Speed is not a big problem. The key is to be able to refit DC motor with high efficiency. Speed can be obtained by changing the speed through belts and gears.
