Taking the device in fig. 1 as an example, the lower end of the permanent magnet 103 is the S pole, and the upper end is the N pole, because the first magnetic conductive member 101 and the second magnetic conductive member 102 made of soft magnetic material are respectively attached to the lower end and the upper end of the permanent magnet 103, the three form a new magnet together, namely the permanent magnet assembly 1, the lower end of the permanent magnet assembly 1 is the S pole, the upper end is the N pole, at this time, the iron core 3 is attached to the S pole of the permanent magnet assembly 1, and the direction of the magnetic induction line in the iron core 3 is leftward as shown in fig. 1; it should be noted that the polarity of the permanent magnet 1 can be reversed, and the iron core 3 can be provided with a magnetic field according to the above principle, and the difference is only that the positive and negative poles of the input current are opposite due to the fact that the magnetic field of the iron core 3 is reversed.

According to faraday's law, the magnetic flux in the initial state and the pressed state is reversed by 180 degrees in the direction of the magnetic induction line, causing a change in the magnetic flux, and further generating induced electromotive force. And the external energy supply triggering module 6 is connected with the coil 4 to form a closed loop, and the signal transmission is provided with enough energy through circuit modification and energy storage. When the external force is released, the iron core 3 will be reset to the original state of attaching to the lower end face of the permanent magnet assembly 1 under the action of the elastic force.

As can be seen from fig. 4, the self-generating device includes a permanent magnet assembly 1 including a first magnetic conduction member 101, a second magnetic conduction member 102 and a permanent magnet 103, a communication channel 2 including a first channel section 101 and a second channel section 202, a swing fulcrum 203, an iron core 3, a coil 4, a coil former 5, an energy supply trigger module 6, an elastic reset member 7, a connecting piece 8 and a connecting piece 9. The permanent magnet 103 is made of rubidium, iron and boron or the like magnetic materials, the upper end face and the lower end face of the permanent magnet 103 are respectively attached with a magnetic conduction piece made of soft magnetic materials to form a new magnet, and the new magnet is arranged in the coil rack 5; coil former 5 is hollowed in the center, and coil 4 has been installed to the outer lane, and iron core 3 passes coil former 5 and magnet contact to open at the other end has a hole, is connected with connection piece 8 through connecting piece 9, and places connection piece 8 in elasticity piece 7 top that resets, utilizes the lever structure between iron core 3 and the coil former 5 to realize the up-and-down reciprocating motion of iron core, and then realizes the change of magnetic flux and arouses the electromagnetic induction phenomenon.
