The electromagnetic induction refers to a phenomenon in which an induced electromotive force is generated due to a change in magnetic flux. The discovery of the electromagnetic induction phenomenon opens up a road for acquiring huge and cheap electric energy for human beings, and has great significance in practical use. If the closed circuit is a coil with n turns, the instantaneous electromotive force can be represented again as: ε is n × Δ Φ/Δ t (Δ t → 0). Where n is the number of coil turns, Δ Φ is the amount of change in magnetic flux, in Wb (Weber), and Δ t is the time taken for the change to occur, in s (seconds). ε is the induced electromotive force generated in units of V (volts). Electromagnetic induction is commonly called magnetic electricity generation and is mostly applied to generators.

The working principle of the self-generating carpet is as follows:

Two ends of the coil are connected with the light emitting diode to form a closed circuit. When the shell is pressed, the coil and the magnet move relatively at the same time, and when the pressure is removed, the original position is restored, so that the coil magnet moves in a relative piston mode. When the magnet is inserted into or pulled out of the coil, the light emitting diode emits light, indicating that an induced current is generated in the circuit. This is because the magnetic flux passing through the coil increases when the magnet is inserted into the coil, and the magnetic flux passing through the coil decreases when the magnet is removed from the coil. The magnetic flux passing through the coil is changed, thereby generating an induced current. The process of inserting or extracting the magnet into or from the coil may be equivalent to the process of conductor cutting the magnetic induction wire. The change in magnetic flux is only the cause of the skin layer generating the induced current, the real cause being also the movement of the charge in the coil by the lorentz force.

For example, in order to improve the cushioning effect, the carpet pedal 20 and the base 10 are both rectangular transparent plates, and the thickness of the base 10 is greater than that of the carpet pedal 20.

The spring 32 is sleeved on the bolt 31 and abutted between the carpet pedal 20 and the base 10, so that when a passenger steps on the carpet pedal 20, a buffering effect can be achieved, and the use touch feeling is improved.
