As is well known, the microwave used in microwave heating devices is an electromagnetic wave. The energy of the electromagnetic wave is much larger than that of the common radio wave, and the electromagnetic wave has the characteristics that the microwave is reflected as soon as the microwave touches metal, and the metal has no way to absorb or conduct the microwave; the microwave can penetrate through insulating materials such as glass, ceramics, plastics and the like, but energy is not consumed; microwaves have the function of heating various medium articles, such as microwave ovens, microwave clothes dryers, microwave water heaters and the like, and are widely applied to daily life of people.

The principle of the electromagnetic field observation method is that induced electromotive forces are generated at two ends of the light emitting diode in an electromagnetic field environment, voltage is provided for the two ends of the light emitting diode, so that the light emitting diode emits light, and the colors of the light emitted by the two ends of the light emitting diode at different positions are different due to the different induced electromotive forces, so that the intensity of the electromagnetic field is distinguished.

Further, the connecting plate may have various shapes, such as square, circle, oval, polygon, etc., without limitation.

Furthermore, the connecting plate may not be provided with or be provided with components for realizing circuit matching for the light emitting diode, such as a resistor, a capacitor or an inductor.
