is whiteboard cleaner poisonous. The working principle is that electromagnetic waves can be propagated through air and insulating objects. The electromagnetic induction type is composed of a pen that can emit electromagnetic waves and is arranged in two horizontal and vertical directions, and the size of the film is the same as the display area. The principle of positioning is that the pen that emits electromagnetic waves emits electromagnetic waves in an intermittent manner. When the pen is close to the film of the receiving coil, the electromagnetic waves emitted by the pen are sensed on the coil. The higher the electromotive force induced by the coil group closest to the pen, the X and Y coordinate positions where the pen is located can be calculated by the electromotive force induced by the horizontal direction and the vertical direction .
