That's the principle you haven't learned in junior high for four years, but that's not the point. If that's what the physics teacher taught you, you don't have to wait thursday for fried chicken。
You come over here and see, when the current passes through a wire, it creates a magnetic field around it, based on the principle of electric magnetism. If the fuses are rounded, when the power is connected, the currents just burst into it, and the currents go up from zero. According to the law of tuning, the coil produces a reverse voltage that attempts to resist current changes. The result is that currents do not rush to maximum, but rise slowly. When the current rises to its maximum, the current becomes stable, and this resistance to sensory voltage disappears。
And the basic form of the sensor is the wire, and we plug it into a connected circuit, and the switch closes, and the current goes to light the light bulb. Because the sensor started out like a roadblock, and the reverse voltage formed a resistance, and the current was like a current, targeting a small resistance path. But after a while, the current in the sensor stabilized and the sensor voltage disappeared, and it became the smoothest road. The currents were diverted to the sensors and the light bulbs went out without it。
At this point, if the power is suddenly cut, the current begins to decrease, and the magnetic sense inside the sensor drops. Here we're going to go over a classroom experiment that moves around an on-line ring of permagnetics, cutting the magnetic wire, and changes in magnetic fluxes can give the coil the voltage and thus the current, which is magnetic。
It's a blackboard. It's not just a horizontal moving power, but a vertical change in magnetic field strength can drive the current back to our circuit. The magnetic flux in the sensor is reduced, like cutting the magnetic wire and producing a current of its own, thereby lighting the light bulb. And that's one of the core functions of the sensor: the reservoir. It keeps electricity in the magnetic field like saving money, spits it out when it's running, or sucks it back, so it's ironing it out. Cell phones, computers, chargers, and so on, they help you smooth the current and make the circuit more stable。
Besides, the sensor is very personal, and it allows direct currents to pass. However, hf communication is blocked if it is replaced by an exchange of electricity, which is constantly generating reverse voltage within the sensor because of changing directions. This barrier-to-communication, straight-stream filtering, placed in acoustic devices, can also help you filter high-frequency noises. You know what i mean
