The anemometer of دی ایرووین ونڈ کپ mainly drives the magnet with eight pole magnetic impact through the wind blade. When the aluminum plate connected with the pointer will produce some eddy current, there will also be magnetic effect. Along with the magnetic field, the magnetism of the magnet and the eddy current on the aluminum disk will also attract and repel each other. Therefore, the faster the wind blade speed is, the higher the pointer will be. The wind vane will point to the wind direction, the thermometer will measure the temperature change, and the measuring cup will be used Measure rainfall.
